What Human Foods are Toxic to Dogs: A Comprehensive Guide

As a dog owner, it's important to be aware of what foods are safe for your furry friend to eat and what can be harmful or even toxic to them. While many human foods can be enjoyed by dogs, some can cause serious health issues or even be fatal. In this blog post, we'll provide a comprehensive guide on what human foods are toxic to dogs.


Chocolate contains a compound called theobromine that can be toxic to dogs. Dark chocolate and baking chocolate are particularly dangerous, as they contain higher levels of theobromine. Symptoms of chocolate poisoning can include vomiting, diarrhoea, tremors, seizures, and even death.

Grapes and Raisins

Grapes and raisins can cause kidney failure in dogs. Even small amounts can be toxic, and symptoms can include vomiting, diarrhoea, lethargy, and decreased appetite.

Onions and Garlic

Onions and garlic contain compounds that can damage a dog's red blood cells, leading to anaemia. Symptoms of onion or garlic toxicity can include weakness, vomiting, diarrhoea, and pale gums.


Avocado contains a compound called persin that can be toxic to dogs. While the flesh of the avocado is not usually dangerous, the seed and skin can cause gastrointestinal upset, including vomiting and diarrhoea.


Xylitol is a sugar substitute that is commonly found in sugar-free gum and other products. It can cause insulin release in dogs, leading to hypoglycemia (low blood sugar). Symptoms of xylitol toxicity can include vomiting, loss of coordination, seizures, and liver failure.


Alcohol can be extremely dangerous to dogs, even in small amounts. It can cause vomiting, diarrhoea, decreased coordination, difficulty breathing, and even coma or death.

Macadamia Nuts

Macadamia nuts can cause lethargy, vomiting, hyperthermia, and tremors in dogs. The exact mechanism of macadamia nut toxicity is not well understood, but it's best to avoid giving them to your furry friend.

Cooked Bones

Cooked bones can splinter and cause blockages or tears in a dog's digestive system. This can lead to serious health issues or even require surgery.


It's important to be aware of what human foods are toxic to dogs to ensure the health and safety of your furry friend. Chocolate, grapes and raisins, onions and garlic, avocado, xylitol, alcohol, macadamia nuts, and cooked bones are all foods to avoid giving to your dog. As a responsible pet owner, it's important to always consult with your veterinarian if you have any questions or concerns about what foods are safe for your dog to eat
