Pet emergency

My dog ate Twinleaf — what to do

Step by step

  1. Take twinleaf 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 twinleaf — FAQ

Is twinleaf poisonous to dogs?

Yes — the ASPCA lists Twinleaf (Jeffersonia diphylla) as mildly toxic to dogs. Jeffersonia diphylla contains berberine and other alkaloids in the roots, historically used in herbal medicine but potentially toxic in significant doses. It is not individually listed by ASPCA as toxic or non-toxic. Based on its alkaloid content and traditional caution around medicinal plants in this family (Berberidaceae), treat as mildly toxic and keep away from pets and children.

How serious is it if my dog ate twinleaf?

Twinleaf 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. Jeffersonia diphylla contains berberine and other alkaloids in the roots, historically used in herbal medicine but potentially toxic in significant doses. It is not individually listed by ASPCA as toxic or non-toxic. Based on its alkaloid content and traditional caution around medicinal plants in this family (Berberidaceae), treat as mildly toxic and keep away from pets and children. 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 twinleaf well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
