Why the Tegu Is the Best Pet Lizard

Dr. Mark is a veterinarian. He works mostly with dogs and exotic animals.

Tegus make great pets.

The Tegu Lizard Pet

If you are among the millions who climb into bed every night dreaming of the best pet, I have the answer you have been looking for. I have owned iguanas, monitors, many other species of smaller lizards, and I currently own about 20 or 30 geckos. (It is hard to keep count since they run free in my kitchen.)

None of them are “the best.” I have found the best, the perfect pet lizard.

The best pet lizard is the Tegu.

Actually, I keep several of these great pets around my house. My oldest, however, lives in my front room. His cage rests on the floor, and when I am eating my breakfast, I flip it open so that he can crawl out and lie in the sun with my dogs. When he gets bored (or maybe just warm-he has never told me which), he goes back to his cage and checks his dish to find out what is for his breakfast.

Tegus are big, mellow, affectionate, easy to care for, and with a good diet can live about 20 years.

Can there be a better pet?

Is the Tegu as Tame as a Dog?

No, Tegus are never as tame as a dog, despite some claims. They are one of the most intelligent of reptiles, and even seem to be interested in humans, at times. Tegus do resist training, though, just like a cat.

They can be as tame as a cat in several other ways.

According to the animal behaviorist Patricia McConnell, one of the big differences between dogs and cats is the way they treat food. If a dog does not have enough, she will feed her puppies (or other dogs in the pack) and go hungry. A cat will take care of her own needs first.

Tegus are like cats in that they always think of number one. They like to eat, do not care too much about what is in their bowl, and do not really care who is doing the feeding.

Yes, many of those Tegus do like kids.

Feeding a Tegu

One of the common complaints about keeping exotic pets is how difficult it is to feed them. Dogs and cats can be fed just by going out and buying food from the pet store. What about a Tegu?

A lot of sites will recommend that the Tegu diet be composed of canned cat food, ground turkey, eggs, and calcium and vitamin supplements.

That diet is okay for a Monitor lizard, but not really needed for a Tegu.

A study of what wild Tegus eat showed that about 2/3 of their stomach contents was actually plants and only a third made up of things like snails, crabs, and other small animals. This makes sense, as in the wild Tegus can usually be found at the base of fruit trees, picking up the fruit that has fallen, and looking underneath for worms or other bugs that they might find.

Here are some suggestions for what you can feed your Tegu. Do not worry if you get things a little wrong. Tegus are forgiving, and not likely to develop nutritional diseases like Iguanas and some other lizards. If you feed your Tegu correctly, he may grow a little slower than those on a potent, high-protein, Monitor-type diet. He might also live longer.

Tegu Diet

If your Tegu has been spoiled by a meat diet, and is relucant to eat veggies,you can make a small plate each feeding and cover it with a raw egg.

Meat, only about 1/3VegetablesFruit




Ground Turkey



Canned Cat Food




Green Beans


Fresh Fish



Fresh Seafood

Greens (turnip, collard, etc)

Tropical (papaya, coconut, guava, etc)

Life With a Tegu

My Tegu does wear a collar (around his waist, not his neck) and I leave it on him all of the time. I only put his leash on when he is strolling around the house or outside in the front yard. The leash is not really necessary in the house, since if he climbs under my bookshelf or bed, my dog will tell me where he is (if I ask nicely). With the leash on I can keep an eye on him if he crawls into a hiding spot.

When he climbs back into his cage, I take the leash off.

Some mornings I will take him out and let him wander around my garden when I am working. I leave his leash on and tie him to a banana tree so that he'll have some shade. He likes this since he can be out in the sun but still hide if he wants.

He does not care for the beach where it is open, and he does not have somewhere to hide. In this, he is very much like a cat—have you ever seen anyone take their cat to the beach?

What Are the Cons to Owning a Tegu?

  • If you do not handle your Tegu, they can become aggressive. They have teeth that will slice through flesh, and wild Tegus are responsible for a lot of the dogs in our area walking around with hunks missing from their noses.
  • They need a large enclosure, or at least a decent sized cage and plenty of opportunities to get out and walk around.
  • My geese do not like the tegus. I think it may be because of the long tail, or maybe it is that tongue flicking out every once in a while. I guess they think a Tegu looks like a snake and when a lizard is sitting in the doorway, they will not even try to go inside.
  • Tegus are not like a dog or cat in that they cannot be trusted with small animals. If you have a hamster, gerbil, or other small animal, it must always be caged when your Tegu is strolling around the house. My parrot can handle himself in a fight, but he always treads carefully when the Tegu is running around the house.

What Are You Waiting For?

But is a Tegu the best lizard to share a house with? Definitely.

Is there anything I regret about having one of these pets? I just regret not getting a Tegu sooner. I have worked around Tegus since the mid-1970s but always thought there was another type of lizard or snake that would fit my family even better.

I was wrong. Tegus are the best pet lizard!

Animals exhibiting signs and symptoms of distress should be seen by a veterinarian immediately.

Questions & Answers

Question: What does a Tegu cost and how much does it take to feed them each month?

Answer: There are many sources of Tegus but a lot of sites will sell young pets for about $200 and some pet shops that stock reptiles might even be a little cheaper. You just need to look around where you live.

As far as monthly expenses, it depends what you feed. Live food costs more so review the foods in the article. (If you want to feed newly hatched chicks I am not a source for that.) Plan on at least $25 per month. You also need to plan on monthly expenses like electricity (heating the cage), vitamins, bedding, and keep something available at all times in case your Tegu needs to see the veterinarian.

Question: As a first reptile pet for a six-year-old, would you suggest an Argentinian B & W over a bearded dragon?

Answer: The reason bearded dragons are selected as first pets for young kids is that they are small and not threatening. The same cannot be said of a tegu. I would not get one as my child's first pet.

I did buy my daughter a corn snake for her first pet. They are small, easy to care for, easy to cage and handle. She did cry when I brought home the pinkies to feed him, but that was many years ago, and feeding pellets are now available.

Question: How would I train or at least show a Tegu who is the boss?

Answer: You do not train a Tegu, and, whatever you do, you should not try the outdated "alpha wolf" techniques to show them you are the top dog. A reptile can be tamed, and can even perform simple tricks using operant conditioning, but you can not ask them to sit on command, nor can you force them to act correctly.

Instead of being the boss, you should focus on being a good owner or a friend of your tegu. Feed him, let him run around your house, and spend time touching him.

Think of him as a pet bobcat, not a dog.

Question: What if you never took care of a lizard before, can you still get and start with a tegu?

Answer: Even if you do not have experience taking care of a lizard, a Tegu is still a good animal to start out wtih. You do need to make sure you have adequate room for a cage, so some beginners will prefer a Leopard Gecko or Bearded Dragon since they are relatively small.

Those lizards do require a diet of insects so can be a lot more work for a beginner.

Question: What cage do you use for your Tegu? Did you make your own?

Answer: I made my own cage. It is a good idea, since Tegus are too large to use an aquarium and most of the containers that are sold commercially.

Make sure that your cage is large enough for your Tegu and has high enough sides (or a lid) so that he does not crawl out.

Question: What is the friendliest, tamest and most docile type of Tegu?

Answer: In my opinion the Argentinian Black and White tegu is the tamest and best animal to work with.

Question: What species of tegu is the best, and what should a beginner owner start with?

Answer: I think the black and white is best. Some people call it the Argentine tegu.

It is fine to start with that species.

Question: I read a lot of articles about salmonella and reptiles--a lot of scary articles saying you have to treat everything the reptile touches as contaminated. How can you let them out to roam a house? Or hang out with them on the couch, etc? Are these articles over kill?

Answer: I would not kiss my Tegu, let him up on the kitchen counter, or share utensils with him. His bowls belong only to him.

As far as wandering around the house though, unless you are immune comprimised there is very little danger. (I cannot tell you absolutely none.)

Yes, I think those articles are overkill. I have heard of a case of a young boy gettig salmonella from kissing his turtle. Again, not something I would recommend.

Question: Is there a good book available for a lizard owner?

Answer: There is a book about "Tegus as Pets" available from Amazon.

Question: Would a huge dog crate be good for a white and black Tegu to stay in at night?

Answer: That is a great idea for a short time period. Just make sure that the screen in front of the crate is small enough so that your Tegu cannot escape.

Question: Where do the Tegus that roam your house poop?

Answer: I have tile on the floor of my front room. They always go there; underneath my hammock where they won't be messed with. It is not a problem to clean up, but they are not housetrained like a dog.

Question: What about the tegu hibernation period? What do you do? How long does it last?

Answer: They do not have a real hibernation, just a period of reduced activity during our winter. It varies between four and seven months.

Tegus will usually stop eating when winter rolls around and locals in my area say that they "eat their tails to stay alive". Actually they just become very thin, so at the end of a winter a Tegu can look pretty emaciated.

Even when my lizards are not eating I open the cage every day, peek in to check on them and will usually put some food in there about once a week. If they do not eat, I toss it the next day.

Question: Is a Tegu lizard good for beginners?

Answer: It depends on the beginner. A Tegu can be a lot harder to handle than a Leopard Gecko or a Bearded Dragon because of his size. If you are concerned about feeding those little lizards, however, a Tegu is a lot better.

I took care of a pair of Tegus when I was 12.

Question: Is the Tegu a rare and endangered animal?

Answer: Tegu lizards are common. They are not an endangered species. If they continue to lose their habitat and the human population continues to encroach on their homes, they may become threatened. Many of the lizards available in the pet trade are bred in captivity.

Question: Can a Tegu and a cat be friends?

Answer: Will they tolerate each other? Sure, since a lot of cats will lose their prey drive around animals in the family. Friends? I doubt it. Tegus ignore a lot but are not really "friends" with most other pets.

Question: Can you use a leash on a tegu?

Answer: Yes, but I attach it to a collar that is around its body just in front of its back legs. If you put the collar on its neck, it will only slip out of it.

Question: What is better as a pet, an adult or juvenile tegu?

Answer: Starting out, definitely a young animal. He will get used to your house, your other pets, your routine, etc. An adult is a lot calmer but may just want to stay in his enclosure all of the time.

Question: Is owning a tegu legal in California?

Answer: According to the website it is legal to keep them as pets in California. If you are looking for a source find someone in your area that sells the lizards and find out if there are any local laws.

Tegus are available at herp shows in California too so you should have no trouble finding someone local.

Question: I am a reptile lover. I am looking for a friend or a pair of friends to help me deal with rats. Are any Tegus voracious rat eaters?

Answer: No, I do not think they would be a good choice. A Tegu might kill a mouse, but if it was a large rat, he would probably leave it alone. A large constrictor might take care of them for you, but also might escape.

I think your best bet to deal with rats is not a reptile but a dog. A small breed with a high prey drive (like a rat terrier, Miniature Pinscher, or a Standard Schnauzer) would be a lot better.

Question: I have had 5 Bearded Dragons and one gopher snake; am I ready for a Tegu?

Answer: It sounds like you have plenty of experience and will make a great Tegu owner. Be sure to read all you can about diet, since feeding your Tegu can be easier than the other pets you have had, but should definitely be done right.

Question: How big are tegus?

Answer: They can get up to about 50 pounds, so imagine a pet as big as a medium sized dog.

Question: Can a Tegus go out to the park and play games?

Answer: No, a tegu is not a good animal to take out to the park.

Many people will tell you that a pet Tegu is like a dog. That is not true. A pet Tegu is more like a cat. He will accept you, and will even be likely to crawl up and set on your lap, but you cannot take him to the beach, do not take him out to play fetch, and you certainly cannot count on him doing a job like herding or guarding.

Question: Does a tegu have sharp teeth ?

Answer: Yes, their teeth are very sharp. They do not bite if handled, but in the wild, they use their teeth to defend themselves against dogs and other animals that attack them.

Question: Can I keep a Tegu if I live in a cold place?

Answer: Your house or apartment is probably heated, so the cold will not be that bad if the Tegu is kept in an enclosure inside the house. So yes, you can definitely keep a Tegu even if the temperature outside is cold.

He will also need supplemental heating like a heat lamp. It is important that you keep a thermometer to monitor the heat in his enclosure, and allow him to have a colder and a warmer area to move about in.

Question: What do I do to assure my Tegu's health during the winter in Canada?

Answer: Your Tegu will need to live inside your house throughout the whole year anyway, so there is no difference during the winter. If your house or apartment is colder during the winter, he will be less likely to come out of his cage, and will spend a lot of time buried in his substrate.

Question: Can I put a Tegu lizard in an open cage with no walls? Would that work?

Answer: It really depends on the Tegu. I prefer to have a cage so that he can climb in and I can close it when my door is open, and the other animals are in the house. If your cage is open and your door is open your Tegu is more likely to escape. (Think of him more like a housecat, not a dog.)

Question: I´ve heard that Rock iguanas are good. What about them as the best pet?

Answer: Since all Rock iguanas are endangered species, they certainly are not a good option. All iguanas, including those available in the pet trade, are herbivores and are a hassle to feed. Tegus are not.

Question: Can a Tegu live in your backyard?

Answer: If you live in a warm region a Tegu could live in your backyard but it is not a good idea. The animal will revert to being wild if it is not socializing with his family. When my Tegu is out in the sun for awhile he begins to become aggressive.

The best thing you can do if you want a pet is to keep your Tegu in your house or apartment. If you just want an animal for breeding this may be an option but do not plan on touching him, and certainly, do not imagine that he is going to want to sit on your lap.

Question: Are chameleons good pets?

Answer: They do not interact that much with people, so a good pet if you want to look but not mess around with the pet much. The main complaint I have heard about chameleons is their short life span.

Question: Is it good to have a hiding spot before I try to tame my Tegu?

Answer: The only hiding spot that your Tegu really needs is his enclosure. If he feels too stressed out by your handling, or you have another pet that is too interested in him, he should be able to climb up and get back into his enclosure.

If you provide too many hiding spots, it is possible to make your Tegu too shy.

Question: Do tegus like it when its cool in the house?

Answer: No, tegus do not really like it when it is cool in the house. If you let your Tegu out to run around make sure that the cage is open so that he or she can go back in to a warm area whenever he wants.

If your house is cool, do not be surprised if your Tegu goes under your bed or another dark spot to curl up. It is a good idea to keep a long leash on him or her so that you can see where he is hiding.

Question: Do Tegus go through a stage of being a lot meaner in the colder months?

Answer: I do not think it is a matter of being meaner. I think that when your Tegu wants to retire from the world for a few months, you should just let him.

He is not a dog and does not have that animal´s ability to tell right from wrong. He is just telling you to back off so he can sleep.

Question: Would a Tegu try to eat a maltipoo or slightly larger poodle mix?

Answer: Actually your dog would be more likely to hurt your Tegu. (Well, at least a Rat Terrier. A Maltipoo, not so much.) I have seen Tegus bite dogs on the nose, but only when defending themselves. Dogs are too large to be considered prey--even a Maltese.

Question: Can a Tegu thrive on an all mouse diet?

Answer: It would not be very natural since they are more likely to eat fruits and other things when out scavenging. I do not think there would be a problem in the short term but in the long term, a Tegu would probably suffer some sort of vitamin deficiency. (I do not think anyone has done any experiments on this, and I am only giving you my opinion.)

Iwan--I have never kept a Tegu with tortoises but I see no reason why you should have a problem. They only attack and eat smaller prey animals so that would leave tortoises out.

-They do okay alone or together, as long as they have enough room.

-I have never managed to potty train one of my Tegus. (It may be possible if you are home all of the time and give a reward when the tegu goes to the right place.) They have an affiinity to go in the same place though so it is fairly easy to clean up after them.

Iwan Wirawardhana on August 06, 2020:

Hello, would you mind if I ask a few questions.

Can a tegu be kept with sulcata tortoises (juveniles & adult)?

Will tegus tolerate each other (for example : do males/females fight?)

Can they be trained to poop & pee at a certain location and what I need to do to train them?

Thanks a lot.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on August 03, 2020:

Mark, they will but it is certainly not necessary to provide them. One reason a Tegu makes such a great pet is that you can open a can of cat food, give him an egg, or even offer a little dish of veggies and fruit.

Mark Dando on August 03, 2020:

Do tegu eat mice/rats?

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on July 29, 2020:

Santiago, no, sorry.

Santiago on July 29, 2020:

i have a question do you know where you can buy a tegu in Peru because i cant find one at all here in peru

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on June 20, 2020:

Bryant, they are great swimmers but not as much as the green iguana. If you let your Tegu swim, be sure the water is not too deep or he has something in the bathtub to climb up onto if he wants out of the water.

As far as illnesses go, no, they do not show many signs. Most die without showing symptoms, like most wild animals.

Bryant on June 20, 2020:

Is it alright to shower them of get them in the water? Are they also prone to heatstrokes? And, for preparation, do they show any signs of illness?

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on April 25, 2020:

Grayson, I am not sure where you are at, but you could start a thread on the Tegu forum "Need experienced Tegu cage builder in "your city". The only website that I know of that sells large enough cages builds them as aviarys for parrots. They are at least $4000 US, do you can do a lot better than that if you hire someone to do the carpentry work.

If you do not get any responses there, try some of the reptile forums on the internet. You are probably already familiar with them since you have bearded dragons. There are a lot of good options out there.

Thanks, Grayson

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on April 25, 2020:

Grayson, no, I do not know where to buy a cage since most people build something to suit the space. If you do not have the space to build then a Tegu is not the best option. They need a lot of room.

Grayson on April 25, 2020:

Do you know where to buy a big tagu cage and do you know what it’s like when a tagu hibernates

Grayson on April 25, 2020:

I would but we can’t build a cage big enough for for a tagu we can’t even build a wall let alone a whole cage for a tagu

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on April 25, 2020:

Grayson, you can probably buy something but since you really need something to fit a specific area most people I know of custom build. Here is a link to a Tegu forum where they discuss what is needed

Grayson on April 25, 2020:

Where do you get a cage big enough for a tagu lizard

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on April 25, 2020:

Grayson, it really depends on how much space you have. Your Tegu will eat your anole and most likely the bearded dragons too. He or she must have a large separate cage.

Grayson on April 24, 2020:

Do you think it would be good if I got a tagu lizard one Anole lizard and three bearded dragons I am also 11 do you think a tagu lizard is good for me

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on February 12, 2020:

Lynn, no, it is not necessary. They rarely get one in the wild. See my chart above for details on feeding.

As far as a checkup goes, I think you need to keep a good eye on your pet and take him in if there are any changes to his attitude or body condition. I am not sure that most veterinarians are more astute than most owners when it comes to looking at a normal pet, but your reptile vet will have the ability to draw blood/check lab results, etc.

Lynn on February 12, 2020:

My daughter has gotten a red tegu. He is large! Is it neccessary to feed live mice/ rats?

We breed rats too and if pinkies die we feed snake & tegu!

How often should tegu go for check up? Thx!

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on August 09, 2019:

Check the chart. There are a half dozen protein suggestions on there, none of which are bugs.

tegu enthusiast on August 09, 2019:

i dont like bugs, so what do i use instead

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on June 28, 2019:

Hi rep lover, I would have to answer this with "sometimes". I am not sure how smart Tegus are but they definitely pick up when people are afraid of them. If the person freaks out, the lizard does too. When I was visiting a friend, she put her Tegu in my lap to see how we would react. (I had never seen him before.) I didnt react, except to pet him, and the Tegu did not react either.

reptile lover on June 27, 2019:

are tegus aggressive to people that they don't know/recognize

Lynn on June 11, 2019:

Dr mark, after reading about Argentineblack and white tegus i just had to have one! Ive owned many reptiles in my life time. I have two bearded dragons at the moment. And just got a juvenile Argentine black and white. He is adorable!. Little skittish but thats to be expected. He did let me pet him though . I loved your article and i wholeheartedly agree that a black and white tegu is the best pet !

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on May 18, 2019:

Hi Froggy Ninja, be sure to let me know. I am sure your Tegu will enjoy him. I would like to add that to the "meat" section of the feeding chart.

The Froggy Ninja on May 18, 2019:

I've been considering obtaining a B&W Tegu for a while, but I am also considering obtaining a microhuman (I think they're called "babbos"?) and was wondering if there would be any dangerous sort of conflict there, despite how Tegus seem to get along well with the larger minihumans.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on April 01, 2019:

Dan, as long as you do not mind the housetraining issue (a tegu will not use a cat box), he can run around your house. If you have carpet you may find yourself cleaning up after him more than you like.

Dan on April 01, 2019:

So can I treat a Tegu similar to a dog/cat and let him/her run free in my house so long as I have a cage for him/her if they need it and give them lots of love/attention? I love the idea of a lizard that I can have roaming my home like a cat (I get that reptiles do need some extra work for diet and temps)

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on March 17, 2019:

Brittany, as long as you are willing to go to the extra expense (like having a really big cage for your Tegu) they are okay to start out with. Best of luck.

Brittany on March 15, 2019:

I have experience with many animals not fully lizards but i been reading about the tegu and i perfer it i know everyone says i should start with a gecko but im 20 something so i think i can handle it since i read alot about animal care and study for it do u think a black and white tegu would be fine

I LOVE TEGUS!!!!!!!!!

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on December 18, 2018:

Jayden, Tegus are not poisonous or venemous.

jayden on December 17, 2018:

Are the Tegu lizards poisonous?

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on August 30, 2018:

Usually in private. What are you talking about?

Vance Nelson on August 30, 2018:

How does a Tegu handle #2 and #3?

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on August 16, 2018:

SariAn, sorry to hear about your dragon. Tegus get pretty large, which is why they are not the best pet for people that do not have room. Figure on at least a meter and a half.

They are not sexually dimorpic.

I guess your Tegu would eat crickets, too, but you would probably have to mix them in with his food!

SariAn on August 15, 2018:

This has made extremely interesting reading. I must admit I had never heard of the Tegu - being firmly in the Beardie Camp for many years. We sadly lost our 9yr old Bearded Dragon (Noddy) very recently following a short illness and a friend told me to look up about the Tegu. I may be sold on the idea but would love to know what length they can be expected to grow up to and is there much difference in size and temperament between the males and females? Their diet seems fairly relaxed, if it means we don't have to have crickets chirruping 24/7 that would be another bonus (although it makes sunny England feel a little more Mediterranean!!).

Look forward to hearing from you :o)

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on August 03, 2018:

Ann, I personally do not feel it would be a good idea to release Tegus into the Everglades. It might happen anyway, as they escape from the pet trade, but it is certainly not something that I would want to do on purpose.

Alligators are cute!! (At least to another alligator;)

Ann Goodman on August 03, 2018:

If tegus eat baby alligators, wouldn't it be good for them to be introduced into Florida everglades? If we have tegus instead of alligators, they would keep the rodents in check and not be a threat to people....

While tegus are a threat to small dogs and cats, same as alligators, apparently, they are not a threat to people.

If I am living in Florida with my grandchildren visiting, I think I'd rather look out on my lawn and see a tegu rather than an alligator!!

Kaz from Atlanta on May 25, 2018:

I commend the author for actually recognizing that cat food is legitimate tegu food.

So many people claim that it can only be raw food. Others have the same superstition about humans.

My tegu is thriving on cat food. I do go out of my way to buy the kind made for silly human "pet parents" who want their carnivorous cat to have peas, carrots, greens, potatoes, and rice. Foolish to give a cat, but my omnivorous Argentine red tegu loves it.

Also, I don't force him to eat foods he doesn't like. Most vegetables, for example. It's silly to mash up food a pet doesn't like in order to mix it with food they do. Nobody mommies their diets in the wild, and they get along just fine.

My own tegu has roam of the house whenever he wants it. He clambers out of his tank about once a day and goes wandering around, maybe comes and stares at me until I feed him, and/or then either goes off to wander around and end up sleeping somewhere, or else comes back and stares at me until I put him back in his tank.

What is the size of a argentine black and white tegu?

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on April 11, 2018:

A lot of cats will lose their prey drive around animals in the family. Friends? I doubt it. Tegus ignore a lot but are not really "friends" with most other pets. They are not dangerous.

borito on April 11, 2018:

and what about a cat?

are they dangerous to them? on March 11, 2018:

I have 2 tegu's a male and female they are pretty adaptable to most situations

Tricia Black on January 03, 2018:

That's pretty awesome. I had not heard of such a lizard! Looks like a great pet! I have dogs and cats, they might now appreciate a lizard. I wonder what those animals think? I was given Dobie Houson's book Devotion which is about communication with our pets. I would love to know what that lizard thinks!!

Is a tegus a beginner , I don't want a gecko because I find them boring I want something I can hold I know people say go for a beardie but I love seeing and looking a tegus and researching them

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on July 04, 2017:

Lily, I keep the collar around his waist because the neck is too thick and he would just slip it off of his snake-like head. They dig a lot, so no need to clip nails. Also you will not need to brush teeth.

I took care of a pair when I was about 13, during breaks from school, and they do okay. They were classroom pets so were used to a lot of noisy kids coming into the class and looking at them every hour.

Handle as much as possible, No problems with the rain, just make sure he has a large cage and somewhere to dig under to get away from it all.

If I take my Tegu out in the yard (for a walk), he gets worked up because of the sun. I would not recommend that, just give lots of freedom at home.

Good luck.

Lily on June 26, 2017:

I have researched several reptiles, but the tegu is the one that has caught my attention the most. I am just wondering: is the tegu an ideal starter pet? I am very inquisitive, so be prepared for a lot of questions:

•Are baby tegus to be handled?

•Is a tegu able to adjust to a different environment tenporarily (holidays, for example).

•Do baby tegus take a while to get adjusted to their environment (for example: you can't handle them for the first few weeks)?

•If well-researched, can tegus make good first pets for beginners?

•Do you have to cut tegus nails/brush their teeth/mist bath them?

•Do tegus panic when it starts to rain (I live in England, so this is a major issue)?

•Are tegus Agressive towards dogs generally, or can a bond be formed from a young age?

•I have noticed your tegu wears a collar around it's waist - is it dangerous for a tegu to have a collar around it's neck?

•If a tegu is taken on a walk in an area with lots of hiding spaces, will it be happier, more likely to escape or just grateful for the freedom?

Kevin W from Texas on May 04, 2017:

This was an interesting read Dr Mark. I'm a reptile lover my self, have a Burmese Python and a Horned Lizard. I've seen a couple of animal shows on Tegu's in Miami and they are portrayed as being very aggressive and will bite off fingers. Guess I should do a little more research on them.

Tegus should not be kept as pets in warm climates on May 03, 2017:

When they escape out into the wild, they breed and become invasive species. See: Florida.

Mark on April 26, 2017:

My son has a black and white tegu he got at a trade show over a year ago that was almost full grown. He keeps it in his room in a 6 by 3 foot cage. The smell is overwhelming when I open the door. I am constantly on him about cleaning the cage. It must be unhealthy to live with that smell in the room. To make matters worse he tells me he has a hard time handling it because it is so aggressive. I'm almost at the point of forcing him to give it up. Is there anything that can be done at this point to calm the tegu down so he can handle and enjoy having it and not be afraid of it every time he opens the door to feed it? The smell is the biggest concern for me and if there is a health hazard for my son in sharing a room with it. Is it a bad idea to keep it in his room? Even with the smell and not being able to handle it my son is adamant about keeping the lizard.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on February 22, 2017:

Ethan, as long as you have plenty of wood shavings or leaves he will dig down and feel secure and happy. A normal cage will do for that.

I am not sure if there are any laws against Tegus in Canada, but I doubt it. As far as him doing well in your house, as long as he has supplemental heat he will do fine there.

Ethan Cross on February 21, 2017:

Hi I was wondering if you meant he actually had to be able to go down/dig in his cage and I was also wondering if it is discouraged to own one of these in southern canada

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on January 23, 2017:

Hi jk1987 the size really depends on how often you are going to let him out to run. An adult needs at least a meter wide, a meter deep, and about 1.5 length, but you can get by with a cage that small only if it is open and your Tegu gets out to exercise. Most of the enlcosures recommended are larger, so even if you get a baby remember that these guys get really big, and if you do not have the space a small lizard is better.

I live in the tropics so do not worry about humidity, but if you are in a drier region you need to get a humidity guage and keep the cage at about 80% humidity. The bedding needs to be sprayed to stay moist, and Tegus like to get in the water when they can (just like Iguanas and Basilisks).

Jk1987 on January 22, 2017:

Hello just held a tegu for the first time and it was an amazing experience what would you recommend size wise would suite a tegu for an inclosure/ home and what humidity level what you have for a tegu. Like your artical very much . Thank you

Benjamin on January 19, 2017:

Hey, so I really want a tegu for obvious reason but I want a baby one so it can grow up with me so I was wondering when do baby tegus hatch, so I can know when to keep my eye out on the web.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on December 21, 2016:

Hi Justin,

Calcium supplementation can be dangerous. If you are giving calcium supplement make sure it is only sprinkled onto his food. What kind of diet is he on? If he is on a good Tegu diet, and is eating whole food like mice, newly hatched chicks, and guppies or other small tropical fish, calcium supplementation is not needed. In any case, it should not be more than 1% of his diet.

We humans are likely to give too much, not too little, and if you give too much calcium supplement he is likely to have kidney stones and hardening (calcification) of his internal organs. Sometimes it can cause constipation also.

Does he have a sunny spot he can sit in when he does come out? I hope you have changed his diet so he can heal naturally. Good luck.

justin crosswhite on December 18, 2016:

Hi, ive recently adopted a rescued argentian black and white tegu. His feet have grown weird due to a calcium deficiency and he obviously hasnt been handled much. Im giving him calcium powder daily and calcium/d3 supplement 2x weekly. Would you have any advice on nursing him back to health?

Hes a little skiddish in his enclosure but once hes out and about hes a sweet heart. Hes already part of the family and i want to get him back healthy. Thanks!

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on December 10, 2016:

Steven, not sure what you meant about height. As far as width, it does not need to be much as long as he can get out and walk around your room. Leave the cage open all the time with plenty of wood shavings as bedding and when he feels the need he can just go in there, burrow down, and escape from it all.

These guys are a lot easier and cheaper to feed than a snake. You can buy a dozen eggs and feed him cheaply, mix it up with some fruit, veggies, and a cheap canned cat food. The cheaper the better since there are more fillers!

Have fun.

Steven Engelhardt on December 08, 2016:

I have a small room and my parents are divorced if i could fit a 8 by 2 by 2 cage in there and let it free roam in my room would that be okay? Also what is the best cheapest diet for these guys because i have 3 snakes and 2 dogs so the food prices are a little high

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on November 09, 2016:

To ??, I deleted your comment because of your use of nasty language. If you are not able to leave a comment without swearing then I am not going to post it.

Just in case you were not aware, there are good and responsible people out there who have never owned a Tegu before.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on September 18, 2016:

Heather, potentially all reptile pets can carry salmonella, but it is not really an issue unless you are immunocomprimised, like to give your Tegu open mouth kisses, or are used to sharing a feeding dish with your Tegu. Seriously, it is not something to worry about. Use common sense by washing your hands after handling your herps and you will be fine.

Heather on September 18, 2016:

Great article! I'm just curious to know, do Tegu lizards carry samonella? I know some lizard species do carry it, but I've heard it's more prevalent in amphibians. Having a hard time finding that information.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on September 10, 2016:

Izzy, we have a dog problem all over the world because inexperienced and irresponsible people get dogs and let them loose when they become large and less fun to handle. Does that mean that only experienced people should get dogs?

Izzy on September 10, 2016:

We have a Tegu problem in the Everglades because of inexperienced and irresponsible owners that let this animals loose when they get too big. Please don't get this as a pet thinking it's like a cat or a dog, this is a large lizard and if you are not experienced with it, it will be too much for you to handle!

Rick on September 10, 2016:

What are your thoughts on how irresponsible exotic pet enthusiasts are allowing non-native species such as the Tegu to get loose and harm native wildlife stocks?

Reilly on July 19, 2016:

HELP! i live in oregon and im not sure where to get a Tegu! anyone know where i can?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on May 02, 2016:

New breeder: Good luck to both of you!

New Breeder on May 02, 2016:

Okay I'm convinced that I will be getting a Tegu Monitor! I have 3 redtail boas and 1 Brazilian rbw board and was thinking about getting a Retic or a Burmese python then I seen someone trying to get rid of a Tegu witch was spoken for but started reading up on these and makes want one better temperment not as expensive to feed, and I have cats and dogs too! Just seems to be a great pet! Thank you

Snakesmum on December 31, 2015:

Hi again, Yes, I'll certainly check out Pinterest for your tegu pics. I don't think I've ever seen one in any of the Australian zoos I've visited.

You're right - often the response to telling people I have pet snakes is "Eww, gross" or an expression of pure horror. Reptiles are fascinating, not gross.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on December 30, 2015:

Oh, they do well without the worms or cat food! That is the best part of the beasts, as they will eat about anything--guinea eggs from my incubator, hot dogs, etc. I have offered mine several types of seafood but he does not like that, for some reason.

They are native here to South America or would probably be banned here too. I know you guys have a lot of great Monitors in your part of the world, but I am happy we have the Tegu over here and would not trade them for any other Reptile.

Check my Pinterest page when you get a chance. I have a group board about Tegus and there are some really good pictures on it--a lot better than the ones on here.

It is nice that someone from HP read this without saying "Ewww, gross." I imagine you get that a lot when other hubbers read about your snakes.

Snakesmum on December 30, 2015:

Now you've made me want to get a Tegu! Don't think they are permitted here in Australia though. Your guy sounds like a really great pet. Most of his diet sounds good to me as well. :-) Not the worms and cat food though.....

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on January 04, 2015:

Thanks so much for that nice comment, Teresa. Hearing from people like you makes all of this effort worthwhile.

Teresa Tanasi on January 04, 2015:

great stuff!!! I too think you should write a book. I would lobs to hear your story. In the meantime, the info you offer about animals is great. You keep me company a lot.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on December 13, 2013:

Tegus seem to have a "live and let live" attitude, Alphadogg, so if my dogs don't mess with them they never mess back. There are some hunting dogs around here missing chunks out of their noses, however.

Burmese Pythons are getting a lot of bad press. I expect to see more laws against them in the future, and legislators up your way telling us how they are the Pit Bull of the reptile world. Take care of Buster and keep him under wraps.

Kevin W from Texas on December 13, 2013:

Great hub Doc, I am also a reptile lover, I have a 9 ft Burmese Python named Buster that I absolutely love. I don't have a lot of knowledge/experience with the Tegu. I did watch a documentary about how they (along with the Burmese & African Rock Pythons) were a problem in Florida. The showed perceived them as extremely aggressive, & with those teeth, I would want my kids/dogs losing a limb.

Mark dos Anjos DVM (author) from The Atlantic Rain Forest, Brazil on December 12, 2013:

Thanks grand old lady! Even if you are not a reptile person (is there such a thing?) I hope you liked their pictures. Despite Bob´s comment on their being "underwhelming", I think they are pretty fantastic.

If you are into that sort of thing, of course!!!!

Mona Sabalones Gonzalez from Philippines on December 11, 2013:

I don't really like reptiles, but I was interested in learning about tegus and why they are great pets. You certainly have a lot of animals in your house! Wonder if I'll end up seeing your home in a TV show or something...

The article is very interesting, and your home sounds most intriguing.

Bob Bamberg on August 01, 2013:

Interesting read. I was a zoo docent in the 90's and we had a tegu as one of our education animals. My knowledge of them was limited to bullet points (range, habitat, diet, reproduction, etc.). Had I known they were as much fun as you indicate, I'd have worked with our's more.

I preferred to work with our ball python, emperor scorpion, or red phase screech owl because they elicited a greater response from the public. The tegu, unfortunately, seemed to underwhelm people. Voted up and interesting.

Elizabeth Parker from Las Vegas, NV on July 31, 2013:

I never heard of them, so thank you for sharing! I think my house is currently capped with three dogs, and I don't know much about caring for a lizard, but for someone who does, this is a very educational hub. Voted up!

WillStarr from Phoenix, Arizona on July 30, 2013:

You need to put all of this in a book, Doc!
