Pet ingestion lookup
My dog ate Clematis - what should I do?
Clematis spp.
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Excessive salivation, vomiting, diarrhea, and potential irritation of the mouth or throat.
Escalation note
While usually mild, ingestion can lead to digestive upset. Always consult a veterinarian if you suspect your dog has ingested this plant.
What to watch for
Drooling, lip-smacking or pawing at the mouth, vomiting, and diarrhea. A large dog that ate vines or flowers can still get meaningful GI upset; watch for oral redness or small ulcers.
Time window
Specific timing not documented. In practice, oral irritation begins within minutes; GI signs typically begin within an hour and resolve in 12–24 hours.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) if drooling persists more than a couple of hours, if vomiting or diarrhea repeats, or if your dog refuses food or water.
What this means for your dog
Dogs that chew clematis vines along a fence usually self-limit because of the protoanemonin irritant — it stings the mouth on contact. ASPCA still classifies clematis as toxic to dogs, but most exposures stay in the mild GI/oral irritation range rather than escalating to systemic illness.
