Onions belong to the Allium family of vegetables which includes garlic, shallots, and leeks. These vegetables contain a compound called N-propyl disulfide, which is toxic to dogs. When dogs eat onions, the N-propyl disulfide damages their red blood cells, leading to a condition called hemolytic anemia. Hemolytic anemia can be fatal if left untreated.

All parts of the onion plant are toxic to dogs, including the bulb, leaves, and stem. Even small amounts of onion can cause problems for dogs, so it’s important to keep them away from any food that contains onions. This includes onion rings, onion soup, and onion powder.
