Is Mashua toxic to dogs?

Tropaeolum tuberosum

Mildly toxic to dogs

Mildly. The ASPCA lists mashua as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Mashua tubers contain glucosinolates and isothiocyanates (similar to mustard and horseradish), which are mildly irritating and in large quantities can suppress thyroid function. Cooked tubers lose much of their pungency and are traditionally consumed as food in the Andes. Not individually assessed by ASPCA for pets; owing to glucosinolate content, keep raw tubers away from pets and children.

What to do if your dog ate mashua

  1. Remove any plant material from your dog's mouth and move mashua 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 mashua to the appointment so it can be treated correctly.

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