What should I do if my dog ate Buttercup?

Take any plant remnants out of the mouth and away from the dog. Offer fresh water but do not induce vomiting and do not give human pain or stomach medications. Call your vet or Pet Poison Helpline before transport so they can stage care — a vet may want to start activated charcoal or IV fluids on arrival, depending on how much was eaten. Call your vet or Pet Poison Helpline (855-764-7661) for any persistent drooling, repeated vomiting, visible oral ulcers, or refusal to eat. Call immediately for small or young dogs, for any neurological signs (weakness, unsteadiness), or if the dog ate a large amount of plant material — IV fluids and anti-nausea medication may be needed.

What this means for your dog

Dogs are far more likely than cats to chow down on Buttercup before the bitter taste stops them — bigger appetites, less discriminating palates. The plant's protoanemonin oil blisters mucous membranes, so a dog that's eaten a real mouthful can develop painful oral ulcers along with vomiting and diarrhea. Pet Poison Helpline notes fatalities are rare, but the GI upset can be significant.

What to watch for

Heavy drooling and pawing at the mouth come first, often with a foul-smelling mouth from blistering. Then expect vomiting, diarrhea, and abdominal pain. ASPCA and Pet Poison Helpline also list depression, anorexia, and a wobbly gait; with very large ingestions, weakness or labored breathing have been reported. Stool may have blood if the GI tract is significantly irritated.

Time window

Signs typically appear within 3–6 hours of ingestion. Most dogs recover in 24–48 hours with fluids and a bland diet; oral ulcers can take several days to heal and a soft diet for about a week is commonly recommended.

When to call the vet

Call your vet or Pet Poison Helpline (855-764-7661) for any persistent drooling, repeated vomiting, visible oral ulcers, or refusal to eat. Call immediately for small or young dogs, for any neurological signs (weakness, unsteadiness), or if the dog ate a large amount of plant material — IV fluids and anti-nausea medication may be needed.

First aid at home

Take any plant remnants out of the mouth and away from the dog. Offer fresh water but do not induce vomiting and do not give human pain or stomach medications. Call your vet or Pet Poison Helpline before transport so they can stage care — a vet may want to start activated charcoal or IV fluids on arrival, depending on how much was eaten.
