Are onions bad for dogs?

Yes, onions are very bad for dogs, and you should avoid them at all costs and in all forms. We love onions, and many famous dishes have onions included in the recipe. Humans that eat a lot of onions will have bad breath, but dogs can have serious health complications that can have tragic consequences.

Are onions toxic?

Onions contain a chemical called N-propyl disulfide, which might be fine for us, but it causes a breakdown in red blood cells in dogs. Red blood cells are vital because they transport oxygen to all parts of the body. If the dog doesn’t have enough red blood cells, they will become anemic and potentially die. There is another problem that happens when a dog eats onions because the toxin attaches itself to the red blood cell. The dog’s body reacts as it would towards an invader and starts destroying the cells. This type of anemia is called hemolytic anemia.
