My dog ate Caltha palustris — what to do
Step by step
- Take caltha palustris away and remove any plant material from your dog's mouth so they cannot eat more.
- Note roughly how much was eaten and when — this helps the vet judge the risk.
- Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
- 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.
- 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 caltha palustris — FAQ
Is caltha palustris poisonous to dogs?
Yes — Caltha palustris (Caltha palustris) is regarded as toxic to dogs, based on genus- and family-level toxicity data. Marsh marigold belongs to the buttercup family (Ranunculaceae) and contains protoanemonin, the family's irritant toxic principle. While Caltha palustris is not individually named on ASPCA's list, the protoanemonin in Ranunculaceae causes drooling, oral and gastrointestinal irritation, vomiting and diarrhoea in dogs and cats. Treat as toxic and keep pets from chewing it; contact a vet if ingestion occurs.
