6 Foods You Must Avoid Feeding Your Dog

Updated on January 15, 2018

When it comes to pets, especially dogs and cats, there are certain foods they can digest and some foods that may be potentially poisonous. Most dog owners know what foods they may and may not feed their dogs. However, there may be many people who may have newly become dog owners or may not yet what they can feed their dogs. If you are one of them, here is a list of 6 foods to avoid for dogs, as they may potentially kill your dear pet.

1) Caffeine

Caffeine in any form is a strict no for your pet dog. Caffeine can be found in coffee, tea, coffee beans, caffeine pills and even chocolate. Caffeine can easily damage your dog’s kidney, heart, lungs and its central nervous system. Typical symptoms include hyperactivity, vomiting and restlessness, followed by increased heart rate, panting, muscle tremors, drunken gait and convulsions.

2) Chocolates/Cocoa

Chocolate in any form is as dangerous to a dog as caffeine. Darker the chocolate, higher the danger to the dog. The main reason for chocolate being poisonous is its cocoa. Hence, cocoa ingestion in any form can prove fatal to the dog. The chemical theobromide present in cocoa can cause damage to the kidneys, heart, lungs and the central nervous system. It is not only the dark chocolate that causes damage, but also the milk chocolate that can cause damage. Typical symptoms include seizures, tremors, and over-excitement, diarrhea, vomiting, hyperthermia, abnormal heart rhythm and coma.

3) Onions, Garlics and leeks

Some of the foods to avoid for dogs include vegetables such as garlics, leeks, onions and chives. These vegetables can cause Heinz body anemia, a type of hemolytic anemia where red blood cells are destroyed. This may be followed by kidney damage. Some other symptoms may involve rapid heart rate, pale gums, vomiting, diarrhea, lethargy and bloody urine.

4) Bread dough

Bread dough or any kind of bakery dough easily makes your dog’s stomach swell. This can cause your dog’s abdomen to stretch, which can cause severe pain. In addition, when the yeast ferments, it produces ethanol which is very toxic for your dog. It may cause damage to the central nervous system as well as the respiratory system. Some symptoms include depression, sedation, weakness, hypothermia and drunken gait.

5) Macadamia Nuts

These nuts may not be fatal, but they do cause illness in your dog. The mechanism of toxicity is yet unknown. A handful of these nuts can cause adverse effects in your pet dog. Some symptoms are weakness, depression, vomiting, muscle/joint pain, joint selling and drunken gait.

6) Currants. Grapes and Raisins

Fruits such as grapes, raisins or black currants are good for humans but not dogs. In dogs, these fruits can cause irreparable damage to the kidneys, possibly causing death. Although the exact toxic dose is not yet established, even 4-5 raisins or grapes can prove poisonous for dogs. If ingested, your dog may show symptoms such as losing appetite, vomiting, abdominal pain, diarrhea, weakness, drunken gait and decrease urine production (leading to complete lack of urine production).

Some other foods to avoid for dogs include fatty foods, artificial sweeteners, and ice cream, alcohol and dairy products. You can however give your dog vegetables such as carrots, green beans, apples, bananas oranges and watermelons. You can also feed your dog lean meats and the regular dog foods available at the mall. Make sure that you feed your dog only those foods that give them the required nutrition and safe for them.

        We actually prepare our dogs food instead of buying dog food. For anyone who makes their own dog food, knowing what foods and seasonings dogs cannot have is just as essential as knowing what foods that are healthy for dogs to consume.

        Well done!

        Very informative hub. I was surprised at how many people still feed grapes to their dogs. One woman in the supermarket was buying grapes FOR her dog! I promptly told her how dangerous they were. My dogs love carrots- great alternative to a dog bone every once in a while and less calories for them. Voted up and useful!

        When i was young, my mom fed our dog eggs with rice. Sometimes, if he is lucky, our dog might get sardine fish mix with rice. He never had dog biscuits or dog food. Just ate whatever we ate, not left-over food. That's unkind. Glad to know some food that dog shouldn't eat. Voted useful

        nerdmama7 : True :) Good that you are already doing some research. Chocolates and onions (and the related family) are indeed extremely bad for dogs. All the best for you and your new family member :)

        Wow. You only hear about dogs having a bad reaction to chocolate. I never knew about any of these! I don't have a dog currently, but want to have a puppy in the next year, so I'm doing my research. I know a lot of people who feed their dogs ANYTHING, and I will have to warn them, because there are some seriously dangerous effects.

        This is great to know. I knew not to give my dog anything in the onion family, chocolate or grapes/raisins but I did not know about the rest. Thanks so much, very informative.

        Thanks for the great advice! I make home-cooked meals for my 12 year old dog. She had a bladder stone which had to be surgically removed about five or six years ago. It turned out to be 100% magnesium. Since then I tried different brands of dog foods that didn't contain magnesium, and after a while I realized that she was better off eating fresh home-cooked meals. I supplement her meals with a few drops of cod-fish oil which is important for every dog's diet.

        This is a great article, and I'm sure a lot of pet owners will find this information useful.

        A vet friend tells me that basically you can feed them any veggie provided it is seed free. Like Mum's, my dog gets peas, carrots, potato and the odd piece of broccoli.

        Things like tomato (although a fruit) are also a definite no go for dogs because of the seeds.

        I usually never fed my dog any veggies. But would love to know about what other veggies you could feed him :)

        My chocolate Lab loves his vegetables. His favourite is mashed potato, but is also partial to broccoli and carrot.
