Is Lavender Safe for Dogs? Lavender Toxicity & Pet Safety
Is lavender safe for dogs? Learn about lavender toxicity risks, safe exposure levels, symptoms of poisoning, and what to do if your dog ingests lavender.
Lavender contains linalool and linalyl acetate, compounds that are toxic to dogs when consumed. While the scent of lavender in aromatherapy is generally considered low-risk, ingestion of lavender plants, essential oils, or concentrated products can cause vomiting, diarrhea, and central nervous system depression. The ASPCA lists lavender as toxic to dogs, cats, and horses.
Can Dogs Eat Lavender?
No, dogs should not eat lavender in any form. The plant Lavandula angustifolia (common lavender) contains two primary toxic compounds: linalool and linalyl acetate. These naturally occurring terpenes are responsible for lavender's distinctive scent but can cause significant gastrointestinal and neurological symptoms in dogs.
The toxicity level depends on the form of lavender:
- Fresh or dried lavender plants: Moderate toxicity risk — most dogs would need to consume a significant amount to show severe symptoms, but even small quantities can cause stomach upset
- Lavender essential oil: HIGH toxicity risk — extremely concentrated, even a few drops can cause serious poisoning
- Lavender-infused products (lotions, candles, sachets): Variable risk depending on concentration and whether the dog can access and ingest the product
- Lavender-flavored treats or foods marketed for humans: Risk varies, but any product containing actual lavender extract poses a toxicity concern
According to the ASPCA's toxic plant database, lavender is classified as toxic to dogs, with symptoms typically involving gastrointestinal distress. The Merck Veterinary Manual notes that essential oils, including lavender, can cause both topical irritation and systemic toxicity when ingested or absorbed through the skin.
What Happens If My Dog Eats Lavender?
Symptoms of lavender toxicity in dogs typically appear within 1-4 hours of ingestion and can range from mild to severe depending on the amount consumed and the concentration of the product.
| Severity Level | Symptoms | Typical Onset | Action Required |
|---|---|---|---|
| Mild | Drooling, mild nausea, decreased appetite, lip licking | 1-2 hours | Monitor closely, offer water, call vet for guidance |
| Moderate | Vomiting, diarrhea, lethargy, abdominal discomfort | 2-4 hours | Contact veterinarian, monitor hydration |
| Severe | Depression, ataxia (uncoordinated movement), tremors, difficulty breathing, liver damage (with essential oil ingestion) | 1-6 hours | Emergency veterinary care immediately |
Essential oil exposure carries the highest risk. Even small amounts of lavender essential oil — as little as 5-10 mL for a medium-sized dog — can cause severe symptoms including liver damage and central nervous system depression. Topical application of undiluted essential oil can also cause chemical burns and systemic absorption.
Are There Any Safe Amounts of Lavender for Dogs?
There is no established safe serving size of lavender for dogs because it is not considered a safe food. Unlike some human foods that can be fed in controlled portions, lavender has no nutritional benefit for dogs and carries inherent toxicity risks at any dose.
Some pet product manufacturers market lavender-scented calming aids or supplements, but these typically use synthetic fragrance or extremely diluted extracts that differ significantly from actual lavender plant material or essential oils. Even with these products, you should:
- Verify the product is specifically formulated and tested for canine use
- Check for veterinary approval or recommendation
- Follow manufacturer dosing instructions exactly
- Monitor your dog closely for any adverse reactions
If you're seeking calming solutions for an anxious dog, consult your veterinarian about evidence-based options such as prescription anti-anxiety medications, veterinary-recommended supplements (like those containing L-theanine or casein hydrolysate), or behavior modification training using positive reinforcement methods.
Lavender Products to Keep Away From Dogs
Beyond the plant itself, many household products contain lavender in forms that pose risks to curious dogs:
- Essential oils and diffusers: Both the concentrated oil and the mist from diffusers can cause respiratory irritation and toxicity if inhaled in large quantities or ingested
- Dried lavender sachets: Often placed in drawers or under pillows, these can be attractive to dogs who like to chew on fabric
- Lavender candles: While the scent alone is low-risk, dogs who chew on candles risk burns, intestinal blockage from wax, and toxicity from concentrated fragrance oils
- Lavender-scented cleaning products: Many contain synthetic fragrance rather than actual lavender, but some use real essential oils
- Lavender bath products: Lotions, bath salts, and soaps may contain essential oils that are toxic if licked off skin or ingested directly
- Lavender plants in gardens: Fresh plants are accessible to dogs who like to graze or dig
Related Plants and Products to Avoid
If your dog has been exposed to lavender, be aware that other plants in the same family or with similar compounds also pose risks:
- Other Lavandula species: Spanish lavender (L. stoechas), French lavender (L. dentata), and hybrid lavandins all contain similar toxic compounds
- Other essential oils: Tea tree, eucalyptus, peppermint, citrus oils, pennyroyal, pine, wintergreen, and ylang-ylang are also toxic to dogs
- Mint family plants: While not all are toxic, some mint-family herbs contain compounds that can cause digestive upset in large quantities
What to Do If Your Dog Ingests Lavender
If you suspect your dog has eaten lavender or been exposed to lavender essential oil, take these steps immediately:
- Remove your dog from the source: Prevent further exposure by securing the plant, product, or area
- Identify what was ingested: Determine the form (plant, oil, product), approximate amount, and time of ingestion
- Do NOT induce vomiting unless directed by a veterinarian: Some substances can cause more damage coming back up
- Call your veterinarian or emergency vet clinic immediately
- Contact ASPCA Animal Poison Control: (888) 426-4435 (available 24/7, consultation fee applies) or Pet Poison Helpline: (855) 764-7661
- Repeated vomiting or inability to keep water down
- Diarrhea with blood or mucus
- Tremors, seizures, or uncoordinated movement
- Difficulty breathing or rapid breathing
- Extreme lethargy or collapse
- Signs of abdominal pain (whining, restlessness, hunched posture)
- Known ingestion of lavender essential oil (any amount)
Prevention: Keeping Your Dog Safe Around Lavender
The best approach to lavender safety is prevention:
- Garden planning: If you grow lavender, plant it in raised beds or fenced areas your dog cannot access. Consider dog-safe alternatives like rosemary, basil, or thyme for accessible garden spaces
- Indoor storage: Keep essential oils, sachets, and lavender products in closed cabinets or high shelves
- Diffuser safety: If you use essential oil diffusers, ensure the room is well-ventilated and your dog can leave the area. Never diffuse oils in enclosed spaces where your dog is confined
- Supervision: When visiting gardens, farms, or homes with lavender plants, keep your dog on leash and monitor their behavior
- Product selection: Choose dog-specific calming products that have been formulated and tested for canine safety rather than human aromatherapy products
When to Consult Your Veterinarian
Beyond emergency situations, talk to your veterinarian if:
- Your dog has a history of eating plants or non-food items (pica behavior)
- You're considering any aromatherapy or calming products for your dog
- Your dog shows repeated gastrointestinal symptoms after potential exposure to household plants or products
- You want recommendations for safe, evidence-based anxiety management for your dog
Your veterinarian can provide personalized guidance based on your dog's size, health status, and specific risk factors. They can also recommend safe alternatives for any wellness goals you were hoping to address with lavender.
Can lavender scent alone harm my dog?
Simply smelling lavender (from a plant or lightly scented product) is generally not harmful to dogs. However, concentrated essential oil diffusers in poorly ventilated spaces can cause respiratory irritation. If your dog shows coughing, sneezing, or breathing changes around diffused oils, discontinue use and ventilate the area.
Is lavender oil safe for dogs if diluted?
No. Even diluted lavender essential oil carries toxicity risks for dogs. The concentration of linalool and linalyl acetate remains significant even at low dilution ratios, and dogs may lick treated skin or fur, leading to ingestion. Never apply essential oils to your dog without explicit veterinary direction.
What should I do if my dog licks lavender lotion off my skin?
A small lick of lavender-scented lotion is unlikely to cause serious harm, but monitor your dog for vomiting, diarrhea, or lethargy over the next 24 hours. If the product contains actual lavender essential oil (check ingredients for "Lavandula angustifolia oil"), contact your veterinarian for guidance based on the amount potentially ingested.
Are there any safe calming alternatives to lavender for dogs?
Yes. Evidence-based calming options include Adaptil (dog-appeasing pheromone) products, supplements containing L-theanine or milk protein hydrolysate (like Zylkene or Anxitane), prescription anti-anxiety medications from your veterinarian, and behavior modification training using positive reinforcement. Always consult your veterinarian before starting any calming supplement or medication.
Can puppies eat lavender?
No. Puppies are at even higher risk from lavender toxicity due to their smaller size and developing systems. Keep all lavender products completely away from puppies, and puppy-proof your home and garden accordingly.
