They Look Safe, But Onions Are a Disaster for Your Dog’s Health If you’re a dog owner, you’re probably familiar with the breed cliché: “They look safe,” but sometimes the harmless-looking foods can actually pose serious risks. Nowhere is this more true than with onions—common in kitchens, salads, and even some human foods—but utterly dangerous for your furry friend. ### Why Onions Are Toxic to Dogs Onions—including raw, cooked, dried, and powdered forms—contain compounds called thiosulfatess, which are highly toxic to dogs. These substances damage red blood cells, leading to a condition called hemolytic anemia, where red blood cells rupture and fail to carry oxygen throughout the body. Even small amounts can lead to negative effects, with severity increasing based on your dog’s size.
