My dog ate Mondo Grass — what to do

Step by step

  1. Take mondo grass away and remove any plant material from your dog's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My dog ate mondo grass — FAQ

Is mondo grass poisonous to dogs?

Yes — the ASPCA lists Mondo Grass (Ophiopogon japonicus) as mildly toxic to dogs. 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.

How serious is it if my dog ate mondo grass?

Mondo Grass is mildly toxic, so most dogs get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your dog ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. 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. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my dog vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep mondo grass well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
