Studies show that the N-propyl disulfide toxin in onions targets your dog’s red blood cells by binding with the oxygen molecules found in those cells. When N-propyl disulfide reacts with oxygen, the result is that it restricts the ability of red blood cells to carry oxygen. This results in a false signal being sent to your dog’s body, which then destroys the red blood cell as if it were an invader. The process involved is known as hemolysis. It results in anemia.
