Frequently asked questions
- Is the lavender plant toxic to dogs?
- Yes. The ASPCA lists lavender (Lavandula angustifolia) as toxic to dogs. It contains linalool and linalyl acetate, which can cause nausea, vomiting, and loss of appetite. In most cases ingestion of small amounts of the plant causes only mild gastrointestinal upset, but it is not a non-toxic plant.
- Is lavender essential oil more dangerous than the plant for dogs?
- Yes. Concentrated lavender essential oil contains far higher levels of linalool and linalyl acetate than the raw plant. Ingestion of essential oil, or applying it to the skin, poses a greater risk than nibbling the plant and should be avoided. Dogs are also more sensitive to concentrated essential oils than humans.
- What should I watch for if my dog eats lavender?
- Watch for nausea, vomiting, and refusal to eat (inappetence) per the ASPCA. Signs are usually mild, but if your dog ate a large amount, consumed essential oil, or shows persistent vomiting or lethargy, contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
