​10 toxic foods you shouldn't give your dog

From avocado skin to macadamia nuts, here are ten foods you should avoid giving your dog as they can cause serious health problems.

It's well-known to many dog owners that chocolate can cause serious problems for dogs. However, there are a number of common foods you're likely to have in your home, which can cause pain, distress and more serious problems for your pet.

Artificial sweetener

Xylitol is an artificial sweetener found in chewing gum, toothpaste and other products, and is derived from hardwood trees. Excessive consumption of xylitol can cause bloating, flatulence and diarrhea in humans—but for dogs, xylitol is toxic. It's important to keep products containing xylitol away from where your dog can eat them, even accidentally.


Unlike in humans, dogs' kidneys can't process alcohol effectively, which can cause them medical problems. Fresh, clean water is best for your dog.


It's not the flesh of an avocado, but the pit, skin, and leaves that can cause harm to your dog. These contain a substance called persin, which causes vomiting and diarrhea.


While caffeine is not toxic to dogs, it does have the same effect on them as humans—and because they are more sensitive to these effects, it can be very unpleasant and uncomfortable for them. If your dog consumes even a small amount of caffeine, it may become hyperactive or start to have tremors.


It's well-documented that chocolate is highly toxic to dogs. This is because of theobromine, a stimulant which interrupts your dog's metabolic processes. Dark chocolate is particularly high in theobromine, making it even more dangerous for dogs. Depending on the amount they have consumed, a dog might suffer from an upset stomach, heart problems, internal bleeding or even death.

Fried and fatty foods

Just as fried and fatty foods can be bad for people, they can also be bad for dogs. High-fat foods can cause your dog to have stomach upsets, plus regular consumption of these types of food can lead to obesity and related health problems.

Garlic and onions

Many people regularly cook with onion and garlic, but for dogs these staple ingredients are toxic. Whether the garlic and onions are cooked or raw, if your dog eats these it can damage their red blood cells, which can then result in anemia.

Grapes and raisins

These fruits are healthy enough for humans but are toxic for dogs. Grapes in particular have a dramatic effect on your dog's health, and can lead to acute and sudden kidney failure.


While they may seem healthy, avoid giving your dog any nuts to eat. Their size makes them a choking hazard, and they are high in fat that can trigger an upset stomach in your pet. In particularly, macadamia nuts have been shown to be highly poisonous to dogs—although they tend not to result in fatalities, they can cause your dog to suffer with fever, an inability to walk, vomiting, lethargy, and tremors.

Milk, cream, and cheese

As dogs grow into adulthood, their ability to digest dairy products decreases as they lack the enzymes to do so. This means they can exhibit signs of lactose intolerance if they eat milk, cream, or cheese, such as vomiting, diarrhea, and an upset stomach.

If you think your dog may have eaten something it shouldn't have, it's crucial to get advice from your vet immediately. You should also keep these toxic foods out of reach of your dog to ensure they only eat what's best for them.
