My dog ate Horse Mint — what to do
Step by step
- Take horse mint 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 horse mint — FAQ
Is horse mint poisonous to dogs?
Yes — the ASPCA lists Horse Mint (Mentha longifolia) as mildly toxic to dogs. Mentha species are listed by the ASPCA as mildly toxic to cats and dogs, causing gastrointestinal irritation (vomiting, diarrhoea) from their essential oils. Horse Mint is not individually listed but belongs to the same genus and contains similar aromatic constituents. Keep pets from consuming large quantities.
How serious is it if my dog ate horse mint?
Horse Mint 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. Mentha species are listed by the ASPCA as mildly toxic to cats and dogs, causing gastrointestinal irritation (vomiting, diarrhoea) from their essential oils. Horse Mint is not individually listed but belongs to the same genus and contains similar aromatic constituents. Keep 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 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 horse mint well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
