Onions, can my dog eat them?

Answer:

No. Onions contain a toxic principle known as N-propyl disulfide. This compound causes a breakdown of red blood cells, leading to anemia in dogs. They belong to the Allium family, a known doggy poison.

The toxin causes oxidative damage to your dog’s red blood cells by attaching to the oxygen molecules in those cells. This reduces the ability of the red blood cells to carry oxygen and also tricks your dog’s body into thinking that the blood cell is an invader. The red blood cell is destroyed in a process known as hemolysis, resulting in hemolytic anemia.

 

Symptoms of Onion Toxicity in Dogs


If you think your dog may have eaten onions, look out for symptoms of anemia, including:

  • Lethargy
  • Weakness
  • Decreased appetite
  • Pale gums
  • Fainting
  • Reddish urine


The ASPCA also lists vomiting, elevated heart rate, and panting as signs of onion toxicity.

If your dog is exhibiting any of these symptoms, the best thing you can do to is get them to a veterinarian as soon as possible.
