Beware of These Foods: A List of What Your Dog Should Not Eat

As pet owners, we love to treat our furry friends with delicious foods, but did you know that some foods can be harmful to your dog's health? While dogs can eat many human foods, there are some that should be avoided at all costs. Some foods may cause mild stomach upset, while others can be extremely toxic and cause serious health problems or can even be fatal.

Here are some common foods that you should never feed your dog:


Chocolate contains caffeine and theobromine, which can be toxic to dogs. Even small amounts can cause vomiting, diarrhoea, hyperactivity, and seizures.
Grapes and raisins: These seemingly harmless fruits can cause kidney failure in dogs. Symptoms include vomiting, diarrhoea, lethargy, and dehydration.

Onions and garlic

Onions and garlic contain compounds that can damage your dog's red blood cells and cause anaemia. Symptoms include weakness, lethargy, and pale gums.


Avocado contains persin, which can cause vomiting and diarrhoea in dogs. In severe cases, it can also cause heart damage.


Just like in humans, alcohol can cause liver and brain damage in dogs. Even small amounts can cause vomiting, diarrhoea, difficulty breathing, and seizures.


Xylitol is a sugar substitute found in many sugar-free gum, candy, and baked goods. It can cause insulin release, leading to hypoglycaemia (low blood sugar), seizures, and liver failure.

Cooked bones

Cooked bones can splinter and cause choking, blockages, or perforations in your dog's digestive system.

Macadamia nuts

Macadamia nuts can cause lethargy, vomiting, hyperthermia, tremors, and in severe cases, temporary paralysis.

Raw dough

Raw dough can expand in your dog's stomach and cause bloating, pain, and vomiting. In addition, raw dough contains yeast, which can produce alcohol and cause alcohol poisoning.


Caffeine is found in coffee, tea, energy drinks, and some medications. It can cause restlessness, rapid breathing, heart palpitations, muscle tremors, and seizures.

Fatty foods

Foods high in fat, such as bacon, sausage, and cheese, can cause pancreatitis in dogs. Symptoms include vomiting, diarrhoea, and abdominal pain.

Milk and dairy products

Many dogs are lactose intolerant and cannot digest lactose, the sugar found in milk and dairy products. Consuming dairy can cause digestive upset, including diarrhoea, vomiting, and gas.


Consuming too much salt can cause excessive thirst, urination, vomiting, diarrhoea, tremors, seizures, and can even be fatal.

Raisins and grapes

Grapes and raisins are highly toxic to dogs and can cause kidney damage or failure. Even a small amount can be harmful, and symptoms may include vomiting, diarrhoea, lethargy, and dehydration. It's essential to keep these foods away from your dog and seek immediate veterinary care if you suspect ingestion.

It's essential to keep these foods out of reach of your dog to prevent accidental ingestion. If your dog has eaten any of these foods, contact your veterinarian immediately.

It's important to remember that even some foods that are safe for humans to eat can be harmful to dogs. Always check with your veterinarian before introducing any new foods to your dog's diet. By being mindful of what your dog eats, you can help ensure they live a healthy and happy life.

In conclusion, it's best to stick to a well-balanced diet specifically formulated for dogs. Always consult with your veterinarian before introducing any new foods to your dog's diet. Your dog's health and happiness are worth the extra effort to ensure they stay safe and healthy.
