My dog ate Great White Trillium — what to do

Step by step

  1. Take great white trillium 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 great white trillium — FAQ

Is great white trillium poisonous to dogs?

Yes — the ASPCA lists Great White Trillium (Trillium grandiflorum) as mildly toxic to dogs. Trillium grandiflorum is not individually listed on the ASPCA Toxic or Non-Toxic Plant database. All parts of the plant — particularly the berries and roots — are understood to contain steroidal saponins that can cause mild gastrointestinal upset (nausea, vomiting, diarrhoea) if ingested by pets or humans. Not considered life-threatening, but ingestion by pets should be monitored and a vet consulted if symptoms develop. Contact ASPCA Animal Poison Control (888-426-4435) for guidance.

How serious is it if my dog ate great white trillium?

Great White Trillium 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. Trillium grandiflorum is not individually listed on the ASPCA Toxic or Non-Toxic Plant database. All parts of the plant — particularly the berries and roots — are understood to contain steroidal saponins that can cause mild gastrointestinal upset (nausea, vomiting, diarrhoea) if ingested by pets or humans. Not considered life-threatening, but ingestion by pets should be monitored and a vet consulted if symptoms develop. Contact ASPCA Animal Poison Control (888-426-4435) for guidance. 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 great white trillium well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
