My 11 lb dog just got into some cooked onions—should I panic or is this something dogs can handle?

This morning, I noticed my 11 lb dog sneaking into the leftover stir-fry with cooked onions on the counter. I've heard that onions can be harmful to dogs, but I'm not sure how much is too much and whether her size makes it more concerning. Should I be panicking and heading to the vet, or is it possible for dogs to handle small amounts of cooked onions without any issues?

Answer

Onions are indeed harmful to dogs, and even small amounts can cause health issues, especially in a small dog like yours.

  • Onions can cause a breakdown of red blood cells in dogs.
  • The size of your dog makes it more susceptible to the effects.
  • Monitor for symptoms and consult a vet quickly if they appear.

Onions contain thiosulfate, which can lead to hemolytic anemia in dogs. Symptoms to watch for include vomiting, weakness, and a reduced appetite. Since your dog is small, it's important to be extra cautious of these effects. If you notice any symptoms, a prompt visit to the vet is recommended.
