There are some fruits and vegetables which you shouldn't give your pet under any circumstances, because they can seriously affect its health.

If you've decided to initiate the BARF diet, or you like to make homemade food for your dog, you must remember that dogs are carnivorous animals, and that green food should only form a small part of their whole diet.

Therefore, here at AnimalWised we will help by giving you a complete list of forbidden fruits and vegetables for dogs.

Avocado, a forbidden fruit

Avocados are, by far, the most poisonous fruit that you can give to your dog. Avocado contains persin, which is a fungicidal substance found in the leaves, seeds and flesh of the fruit itself. Additionally, avocados have high content of vegetable fat and toxins.

If your dog consumes avocado, you can expect for it to experience vomiting, stomach pain and even pancreatitis. Furthermore, if this forbidden fruit is regularly or excessively consumed by dogs, it can cause pulmonary system deficiencies or affect the heart.

Citrus fruits

Whilst many people emphasize the high toxicity of citrus fruits, the truth is that they're not especially harmful, although this doesn't mean that they're an ideal fruit for your dog.

Their high sugar content contributes to obesity. Moreover, excessive consumption of this type of fruit can cause the dog to develop gastrointestinal problems such as vomiting, stomach pain and diarrhea.

Whilst they're not serious, these health problems aren't beneficial for your pet. Avoid giving it citrus fruits - give it other fruits that it can enjoy more.

Onions, garlic, leeks and chives are all toxic vegetables for your dog. Giving dogs these vegetables on a daily basis, or an excessive amount in one go, can cause serious problems. This is because they contain trisulfides, which can destroy red blood cells and thus heighten the risk of anemia.

Grapes are another harmful and toxic fruit for your dogs. Even though the component that makes them intolerable for the dog's body is not yet clear, we can confirm that they cause liver and/or kidney damage. Eating lots of grapes can cause your pet to suffer kidney failure.

Other forbidden vegetables

Raw potatoes, leaves and stalks have a high solanine content, which is toxic for both dogs and humans. As such, and so that you can turn them into an edible food, you need to boil them first. Doing this alone will make it safe to give potatoes to your pet. Remember that similar foods such as raw sweet potato shouldn't be given either.

Raisins and seeds

Other toxic foods for your pet are raisins and seeds. It's important to underscore that you should never give your dog the seeds or stones of fruits such as peaches, apples, apricots, cherries and plums, since they contain a high cyanide content which the dog will be unable to digest.

In any case, remember that you can give your dog the fruits' flesh as long as the seeds or stones are removed beforehand, because it is rich in fiber and healthy in small doses.

Great article! However, I believe it's worth to mention that vegetables like rhubarb or tomato (unripe) can cause dog poisoning as well. Vomiting, diarrhea, and loss of appetite are a few of many symptoms.
