Your Dog’s Dangerous Secret: Onions Can Harm Them Forever As a pet owner, you likely understand the deep bond between you and your furry companion. We share our homes, meals, and most importantly, our love — but sometimes, what’s safe for us can be deadly for our dogs. One of the most significant yet overlooked dangers lurking in your kitchen is onions. ### Why Onions Are Toxic to Dogs Onions—whether raw, cooked, dried, or powdered—contain compounds called n-propyl disulfide and thiosulfate, which are highly toxic to canines. These substances cause oxidative damage to red blood cells, leading to a condition known as hemolytic anemia. Over time, this can permanently harm your dog’s organ function and, in severe cases, result in fatal complications.
