Is Purple Yam toxic to dogs?

Dioscorea alata

Mildly toxic to dogs

Mildly. The ASPCA lists purple yam 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. Raw Dioscorea alata tubers contain cyanogenic glycosides and bitter saponins that are unsafe to eat uncooked. Thorough cooking (boiling or steaming for at least 20 minutes) fully neutralises these compounds. The cooked tuber is safe and highly nutritious. Not individually listed by ASPCA; the genus may cause gastrointestinal upset in pets if raw plant material is ingested.

What to do if your dog ate purple yam

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

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