Onions Are Silent Killers: Why Every Dog Owner Needs to Stop Feeding Them If you love sharing human food with your furry friend, onions deserve your immediate注意—and not the friendly kind. While onions may seem harmless to us, they pose a serious health risk to dogs. Known as silent killers, onions (along with other members of the Allium family like garlic, chives, and leeks) can cause irreversible damage to your dog’s red blood cells, leading to a potentially life-threatening condition called onion toxicity. ### Why Are Onions Toxic to Dogs? Onions contain potent compounds called organosulfoxides and sulfides, which are highly toxic to canines. These substances are absorbed quickly into a dog’s bloodstream, where they trigger oxidative damage to red blood cells—a process that destroys them and prevents oxygen from circulating effectively throughout the body.
