Is Mondo Grass toxic to dogs?

Ophiopogon japonicus

Mildly toxic to dogs

Mildly. The ASPCA lists mondo grass 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. Ophiopogon japonicus is not individually listed by the ASPCA on either its toxic or non-toxic plant lists; it is widely reported as non-toxic but lacks an explicit ASPCA listing, so treat with caution and verify with a vet. No specific toxic principle is documented; ingestion of foliage or the blue berries may cause mild vomiting or gastrointestinal upset in cats and dogs.

What to do if your dog ate mondo grass

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

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