Is Green Shiso toxic to dogs?

Perilla frutescens var. frutescens

Toxic to dogs

Yes — green shiso 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. Perilla frutescens is a documented toxic plant: although not individually on the ASPCA cat/dog list, veterinary toxicology sources (Colorado State University) record it as poisonous to grazing animals via perilla ketone, which causes acute respiratory distress, with general gastrointestinal upset risk to pets. Keep away from cats, dogs, and livestock; verify with a vet on ingestion.

What to do if your dog ate green shiso

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

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