Food Poisonous To Dogs

We recently shared a guide on how to feed your dog and recommended a complete purpose made dog food, whether that be wet or dry. 

Just like humans, dogs deserve a tasty treat now and again or something palatable to add variety to their diet. However, what may be suitable for us, can actually be really harmful to your dog.

Food which is poisonous to dogs:

Here is a simple list of some foods which can be harmful to dogs. Level of poisoning and severity depends on each type of food, how much the dog consumes and whether or not the dog has any underlying health problems.


Probably one most commonly heard of, chocolate is very poisonous to dogs and should never be given, even in small quantities. It is important to store your chocolate out of reach from the dog, e.g. in a cupboard up high, so they can’t be tempted to steal any.


Grapes, raisins, currants and sultanas are all poisonous to dogs, even the dried variety. Avocado is also poisonous as the persin which is found in its leaves, fruit and seed can cause vomiting and diarrhoea. 


Macadamia nuts are poisonous to dogs – they can affect the nervous system resulting in weakness and panting. 


Onions, garlic, leeks, shallots and chives all belong to the Allium family. They contain a substance which can damage red blood cells in dogs and can cause life-threatening anaemia.

Blue Cheese

The fungus found in blue cheeses such as stilton and roquefort can cause muscle tremors and seizures in dogs. 

Cooked Bones

Certain raw bones such as beef or lamb can be given to dogs. But cooked bones can splinter which can perforate a dog’s intestine. Larger bones can cause blockages in the digestive system.
