My dog ate Lesser Burdock — what to do

Step by step

  1. Take lesser burdock 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 lesser burdock — FAQ

Is lesser burdock poisonous to dogs?

Yes — the ASPCA lists Lesser Burdock (Arctium minus) as mildly toxic to dogs. Arctium minus is not listed as toxic on the ASPCA database, and veterinary sources generally regard burdock as non-toxic to dogs and cats. However, the hooked seed burrs are a significant physical hazard: they become deeply entangled in fur, ears, and paws, causing pain, skin abrasions, and potential eye injuries or respiratory irritation from the fine pappus bristles inside the burr. Ingestion of burrs can also cause oral irritation and gut impaction. For these physical reasons the plant warrants caution around pets.

How serious is it if my dog ate lesser burdock?

Lesser Burdock 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. Arctium minus is not listed as toxic on the ASPCA database, and veterinary sources generally regard burdock as non-toxic to dogs and cats. However, the hooked seed burrs are a significant physical hazard: they become deeply entangled in fur, ears, and paws, causing pain, skin abrasions, and potential eye injuries or respiratory irritation from the fine pappus bristles inside the burr. Ingestion of burrs can also cause oral irritation and gut impaction. For these physical reasons the plant warrants caution around pets. 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 lesser burdock well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
