What Is So Bad About Chocolate?

Chocolate is severely toxic to dogs because it contains theobromine. This is a stimulant that affects the nervous system and heart muscle, as well as increasing the frequency of urination.

Dogs can't metabolize theobromine as effectively as humans. This allows it to build up in their system until it reaches toxic levels of concentration. This may lead to a variety of health problems including death due to cardiac arrest.

The less the dog weighs, the more you should be worried because the toxicity levels are higher.

More Dangerous Toxins

Here is a list of other foods that can be highly toxic to dogs:

  • sugarless candies
  • raw salmon
  • onion (large quantities)
  • garlic (large quantities)
  • grapes
  • raisins
  • mushrooms
  • mistletoe berries (we normally don't pay any attention to these during the holidays but our pets do!)
  • caffeine

Of course, there are the normal things to beware of in your household as well, such as anti-freeze, rat poisons, paint thinners, cleaning fluids, and so forth. So if you have a pet in your home, take the same precautions you would if you had a small child.

      Onions, garlic and mushrooms? Are they still toxic to dogs even when they're cooked in a dish? :O

      According to the research I did, it makes no difference if they are cooked or not. It is a million wonders I haven't killed every dog I've had! LOL. My sister has a golden retriever that kept staying sick and she couldn't figure out why. When she got an email about raisins being toxic, she thought about the dog eating raisin bran pretty often. She stopped feeding her the raisin bran and she has been fine ever since. Strange, isn't it?

      Interesting that this request came up just after I published my own hub on substances toxic to dogs. For reference, you can find it at:

      I know. I've fed dogs leftover food with onions, garlic, or mushrooms countless times but they never showed any signs of illness. :O I better be more careful what I feed the dogs from now on. Thanks for the info, Bonnie. :)

      Thanks for stopping by and posting Doghouse! I used to be but was advised by the vet to start giving my dog people food after he became ill from severe iron deficiency after eating dog food for many years. He told me to think healthy. If it was healthy for us it was healthy for them. (As far as meats). I only have one now as my oldest one died at 16 years old. I just boil or bake enough of what meat we are eating for the "babies, or rather baby" to eat with us. He is also healthy and getting old ike his Mama LOL.

      I once had a dog of mine eat an entire solid chocolate Easter bunny. About two years later she developed severe epilepsy. Three years later she died. The dog was only 8 or 9. There is truth here.

      Baker's chocolate should be avoided at all cost, but for the most part milk chocolate doesn't have as much theobromine in it to do anything but cause a minor reaction unless the dog is actually allergic to chocolate, which is usually the case. Most vets say to avoid it, but usually it's to prevent an allergic reaction versus the toxicity of barker's chocolate which can cause severe health concerns, sickness, and death.

      So many people ask, 'my dog just ate a chocolate chip cookie, is he going to be ok?' and the answer is yes unless the dog is allergic to chocolate.

      Rob, epilepsy would not have been caused by a chocolate Easter bunny. It's usually a hereditary disorder but can also be caused by car accidents and other trauma to the brain.

      By the way Bonnie, Bo's a gorgeous dog!

      Hi, Rob! Thanks for stopping by. Whitney is right. The chocolate would have had a reaction a lot sooner if it would have made him ill. I know it is hard to lose one you love. I just lost my peek-a-weenie last year at the ripe old age of 16 and we had him for 12 of those years.

      Whitney, I always appreciate your comments! You always have something good to add. Oh, and I certainly agree about BO! But then I am a bit biased! LOL. My daughter had to raise him on a bottle and at the time we were all in the same house so he was Grammy and Paws baby, too. And to think I used to be one of those who was terrified of a APBT! The only real problem with Bo is that he doesn't understand the concept that Grammy's lap did NOT grow with Bo LOL. He still crawls up in our lap and we groan and grit our teeth until the 100 lbs. of solid rock get situated where he wants to be LOL. He misses Grammy and Paw since they moved and always goes nutso when we he sees us!

      Bonnie, I feel ya! MIA is a blue APBT, 9 months, 60 lbs, and still growing. She doesn't realize she's note 8 pound puppy anymore. She has to nap in you lap or she can't nap at all. She climbs in your lap at the computer. It's ridiculous.

      I do want to add to my previous comment, though. Although, not all dogs are allergic to regular chocolate, I still wouldn't recommend sharing the occassional oreo or M&M. I'd rather be save than sorry and not share chocolate of any kind in order to prevent an allergic reaction and an emergency trip to the vet.

      May I ask why she cropped the ears? And how you guys came to get him before he was weaned?

    • Bonnie Ramsey profile image

      Bonnie Ramsey 8 years ago from United States

      She is here now and she said that their ears were so big that the vet said they were more prone to ear infections. They still have his Mama. Mya. When Mya had her litter, all of them died except Bo and they said it would be best to get him away from Mya in case he was sick because they will kill and eat them if they are ill. That is why he was raised on a bottle. There is a story behind Mya which I intend to cover in my next hub tonight so be sure to watch for it. There will be pics, too. The hub will be called "Is that pawprints I see on your back?"

    • Whitney05 profile image

      Whitney 8 years ago from Georgia

      Hmm.. That's not true, and a major myth to ear croppings. What about beagles and basset hounds with extremely long ears? It's just not true that long ears can increase risk of ear infections, usually lazy people will claim this is the reason to crop dog's ears. Not saying anything about your daughter as the vet told her this, just why other people who claim this do it.

      If you clean the dog's ears, no matter how long, you shouldn't have a problem with ear infections.

      Personally, I'd find another vet.. :-\

    • Whitney05 profile image

      Whitney 8 years ago from Georgia

      I'm entering my link in a separate comment, in case you would prefer it not in the hub. But, I have a hub about ear cropping and tail docking. It's mostly from a personal standpoint towards people who think it's "cool", but it has procedures, pictures, and videos.

      http://hubpages.com/animals/Stylizing-Your-Dog

      Oh, and I slightly touched on the ear infection thing when I wrote it.

      I would also add that the darker the chocolate, the more toxic it is. Milk chocolate needs higher doses to be toxic than dark.

      Fotl, thanks for stopping by and I am glad that you added this as I have been finding that out since posting this hub. I figure I would rather be safe than sorry so Pug knows that chocolate is a "no, no" for him LOL. Fortunately, he never did like it!

      Whitney,

      Thanks for posting your link. I don't mind that when it isrelevant to the hub at all. This is a very important hub and since my daughter is here with us now, I will be showing it to her! The tail docking on Bo's part was the fact that he can seriously abuse a person with that whip! LOL. Jenny said if she ever had another one she would keep the ears and dock the tail for this reason LOL. He really works on Grammy and Paw because he gets so excited when he is around us. And Lord help us if we have a drink on the coffee table! That thing is like a steel rod and he can just clear the coffee table when he is happily walking by! LMBO!

      I had a Lab that managed to find the Easter Bunnie's hiding spot BEFORE he hid the chocolate bunnies from the children.

      Kelli ate about 4 pounds of milk chocolate and the foil wrap around them. When we discovered the shredded remainders of the foil, I was sure that she would be very sick and perhaps die. But neither ocurred. Our vet also indicated that the dog and chocolate combination is more of a wives tale than reality.

      A couple of weeks later this same "chow hound" found the can of cat food that my husband had attempted to open but only succeeded in popping off the key ring.

      We came home after work to shredded cat food label on the floor and not a remnant of the can or the food itself.

      I freaked! This time I was certain Kelli would die from internal bleeding and that it was going to be very messy. I stayed with her for two days awaiting some sign that she was ill.

      I didn't happen.

      Kelli lived to be 14 years old and died because of cancer. We have always been amused and amazed by her 'iron gut'.

      Hi, Coffeconnoisseur!

      Thanks for stoppping by! The level of toxicity will vary from one dog to another. Also, chocolate easter bunnies are usually made from milk chocolate, which is not as toxic as Baker's chocolate. As for the can of cat food, I suppose she had an angel watching over her . Or maybe, like you said, she had an iron gut LOL.

      I have had dogs in the past to eat things they weren't supposed to and survive as well. I guess a lot depends on the dog itself, just as it varies as to what humans can withstand and how their bodies react to certain things. I guess all we can do is try our best to avoid those things that are dangerous to them as much as possible and if they do happen to get something they shouldn't, take the necessary actions to get help. Sounds like Kelli was an amazing pet!

      My dog just ate a small portion of a chocolate chip cookie. Above there is a comment saying their dog ate one & was fine. My pup is a toy poodle & only weighs 6-8 lbs.

      What symptoms would the dog show if it did make him sick?

      This is my 2nd scare as he did get into my Grandchildrens Easter basket, yet back then, we determined he hadn't eaten any at all.

      I'd greatly appreciate any info on the symptoms. Meanwhile, *fingers crossed* all will be okay tonight.

      Bonnie Ramsey 8 years ago from United States

      Coodles,

      Thanks for stopping by! Dogs eat grass normally when their tummy is upset or if their body needs extra protien. If their tummy is upset, the excess protien in the grass will make them either throw up what is irritating them or sometimes will settle their tummy. Hope this helps!

      Josie,

      I'm not sure whether the chocolate was a milk or dark chocolate. Milk chocolate is not quite as toxic as the dark. However, even with milk chocolate, you may want to call your vet and let them know what has happened. Your vet will advise you as to whether to bring him on in or to watch for certain symptoms. I wish you all the best!

    • Josie 8 years ago

      Bonnie,

      thankyou so much for replying. My dog i think is fine, but we did call our vet and he said to look and see if hes acting different or not as active as usual. Franky (my dog) is tottaly fine!!!!!!!!!!

      I had a Chinese pug with whom I shared bags of Hershey"s minatures with all the time / (a bag at a time) and she never got sick, or had any ill effects. She lived to be fifteen years old. did not know the dangers then (70-80's) would never take the chance with Boston Terrier that i have now111111

    • Joni 7 years ago

      If your dog likes to eat cookies with you then there is a way to share the cookie snacks. I was at pet smart the other day and found these carob chip dog cookies. I acually ate a piece and it really does taste almost the same. looks like real chocolate chip cookies and your dog will never ever know the difference. My three yr old ate one and he couldn't tell a difference in them. but besides cookies they have a huge selection of all kinds of niffty snacks.

    • Brett Gravener 6 years ago

      I went to college and earned a certificate in animal care so believe what i say, Dogs cant eat chocolate because when you eat your body digests food rite but with dogs when they eat chocolate it enters their belly and stays there because the acid in their stomach doesn't break it up, only over a few weeks it breaks up, and the best food for a dog is dry food and tinned but i prefer dry because wet food goes off over night, if your dog doesn't like dry food then put gravy in it and the dog will love it just like we do with our sunday dinner. thank you
