My dog ate Blue Vervain — what to do
Step by step
- Take blue vervain 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 blue vervain — FAQ
Is blue vervain poisonous to dogs?
Yes — Blue Vervain (Verbena hastata) is regarded as mildly toxic to dogs, based on genus- and family-level toxicity data. Verbena hastata is not individually listed by the ASPCA. The related Verbena genus contains iridoid glycosides that may cause mild gastrointestinal irritation in dogs and cats if ingested. As a precaution, treat as mildly toxic and prevent pets from consuming large quantities.
How serious is it if my dog ate blue vervain?
Blue Vervain 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. Verbena hastata is not individually listed by the ASPCA. The related Verbena genus contains iridoid glycosides that may cause mild gastrointestinal irritation in dogs and cats if ingested. As a precaution, treat as mildly toxic and prevent pets from consuming large quantities. 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 a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
How do I stop this happening again?
Keep blue vervain well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
