Is Shallot toxic to dogs?

Allium cepa var. aggregatum

Toxic to dogs

Yes — shallot is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Shallots belong to Allium cepa, which the ASPCA lists as toxic to dogs, cats, and horses. The toxic principle, N-propyl disulfide, damages red blood cells and causes Heinz-body haemolytic anaemia. Signs include vomiting, weakness, elevated heart rate, panting, and blood in the urine; every part is toxic whether raw, cooked, or dried.

What to do if your dog ate shallot

  1. Remove any plant material from your dog's mouth and move shallot out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of shallot to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten shallot, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
