The question of “can dogs eat cooked onions” is a common one among pet owners. Onions are a staple in many human diets, but their toxicity to dogs is a well-known concern. Cooked onions are less toxic than raw onions, but they can still cause health problems in dogs if consumed in large quantities.
Onions contain a compound called N-propyl disulfide, which is toxic to dogs. This compound can damage red blood cells, leading to anemia. Anemia can cause a variety of symptoms, including weakness, lethargy, and pale gums. In severe cases, anemia can be fatal.
