My dog ate Great Mullein — what to do
Step by step
- Take great mullein 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 the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and 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.
My dog ate great mullein — FAQ
Is great mullein poisonous to dogs?
Yes — the ASPCA lists Great Mullein (Verbascum thapsus) as mildly toxic to dogs. Verbascum thapsus is not listed on the ASPCA toxic plant database. However, the dense, stiff hairs on leaves and stems can cause contact irritation or mechanical irritation of the mouth and gastrointestinal tract in cats and dogs if ingested in quantity, so 'mildly-toxic' is the prudent classification.
How serious is it if my dog ate great mullein?
Great Mullein 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. Verbascum thapsus is not listed on the ASPCA toxic plant database. However, the dense, stiff hairs on leaves and stems can cause contact irritation or mechanical irritation of the mouth and gastrointestinal tract in cats and dogs if ingested in quantity, so 'mildly-toxic' is the prudent classification. 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 great mullein well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
