What should my dog not eat? Foods poisonous to dogs
Beer / alcohol
“But my dog loves beer!” He might like the taste, but please don’t give it to him. Alcohol can cause coma in dogs and be fatal.
Chocolate contains theobromine, a substance poisonous to dogs. It can cause diarrhoea, vomiting, anxiety and (in extreme cases) fits.
Cooked chicken bones can splinter and cause choking or damage to the mouth. Please don’t assume that cooking the bones will make them soft, as it actually makes them more likely to splinter.
Garlic & onion
Garlic and onions contain thiosulphate, a substance that can irritate a dog’s digestive tract. It can also damage red blood cells and cause anaemia.
Grapes & raisins
Although fruit is not generally bad for dogs, it is better not to give them any grapes (nor, therefore, any raisins). They contain an as yet unidentified substance that is bad for the kidneys of both dogs and cats.
It’s best not to give your dog any raw eggs. These contain avidin, an anti-vitamin that adversely affects the metabolism of fats, sugar, amino acids and energy.
