My dog ate Red Trillium — what to do

Step by step

  1. Take red 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 a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.

My dog ate red trillium — FAQ

Is red trillium poisonous to dogs?

Yes — Red Trillium (Trillium erectum) is regarded as mildly toxic to dogs, based on genus- and family-level toxicity data. Trillium erectum is not individually listed on the ASPCA toxic or non-toxic plant database. Like other Trillium species, it contains steroidal saponins, particularly in the berries and roots, which can cause gastrointestinal irritation (vomiting, diarrhoea) if ingested by pets or humans. Historically the rhizome was used medicinally, but should not be considered safe for unsupervised pet access.

How serious is it if my dog ate red trillium?

Red 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 erectum is not individually listed on the ASPCA toxic or non-toxic plant database. Like other Trillium species, it contains steroidal saponins, particularly in the berries and roots, which can cause gastrointestinal irritation (vomiting, diarrhoea) if ingested by pets or humans. Historically the rhizome was used medicinally, but should not be considered safe for unsupervised pet access. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.

How do I stop this happening again?

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