What happens if your dog ate cooked onions?

There is a whole process of poisoning in your dog. Onion has a compound called N-propyl disulfide which is a sulfur-containing compound. The sulfur-containing compound attaches to the hemoglobin molecule present in the red blood cells. Hemoglobin is responsible for carrying oxygen to body organs. 

N-propyl disulfide causes oxidative damage to the hemoglobin molecule which impairs the activity of this molecule. This causes the formation of Heinz bodies. Heinz bodies are red blood cells but in clump form. These bodies are recognized as foreign agents by the immune system of the body.

The immune system started to kill these bodies. This process is called hemolysis and if left untreated it continues until the body is short of oxygen supply which can lead to tissue necrosis and death of the organs in the body.
