My dog ate Lemon verbena — what to do
Step by step
- Take lemon verbena 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 lemon verbena — FAQ
Is lemon verbena poisonous to dogs?
Yes — the ASPCA lists Lemon verbena (Aloysia citrodora) as toxic to dogs. The ASPCA lists Lemon Verbena (Aloysia triphylla, a synonym of A. citrodora) as toxic to dogs, cats and horses — the toxic principle is its essential oils, with stomach upset and colic as the reported clinical signs. The ASPCA notes small culinary or flavouring amounts are not a concern; the risk is a pet chewing the plant itself. If your pet has eaten lemon verbena foliage, call your vet or the ASPCA APCC on (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK.
