Eucalyptus oil candles flicker softly. The air smells clean, crisp, and calming — but as your dog curls up nearby, a question lingers: Is eucalyptus safe for dogs?
Many pet parents love the scent of eucalyptus for its spa-like freshness, yet few realize it can pose real health risks for pets. The truth is, eucalyptus can be toxic to dogs in both its plant and oil forms. Whether you diffuse it, grow it, or clean with it, understanding how it affects your furry friend is vital for a safe, happy home.
According to ASPCA’s Toxic and Non-Toxic Plants List, eucalyptus contains compounds that may cause drooling, vomiting, or even central-nervous-system depression in dogs.
What Makes Eucalyptus Toxic to Dogs?
The main culprits are essential oils found in eucalyptus leaves and stems — especially eucalyptol (1,8-cineole).
Even tiny amounts of these compounds can irritate a dog’s digestive tract, skin, and respiratory system.
PetMD’s report on essential oil toxicity in dogs confirms that oils such as eucalyptus, tea tree, and peppermint are among the most common sources of accidental poisoning.
Dogs have a stronger sense of smell but weaker detoxification abilities in the liver compared with humans. So what smells refreshing to you can overload your dog’s system quickly.
Eucalyptus Oil Diffusers and Dogs
Many households use diffusers or humidifiers with eucalyptus oil for congestion relief or relaxation. Unfortunately, vaporized oil can harm your dog’s respiratory system, especially in small or enclosed rooms.
Symptoms of inhalation exposure include:
- Coughing or wheezing
- Watery eyes and drooling
- Trembling or disorientation
- Fatigue or weakness
The American Kennel Club (AKC) warns that essential oils in diffusers can cause mild to severe reactions, depending on oil concentration and ventilation.
What to do: Use diffusers only in rooms where your dog can leave freely. Keep the space well-ventilated and avoid direct exposure.
Eucalyptus Plants in Your Home or Garden
The plant itself is just as risky. While some dogs ignore plants, others nibble leaves out of curiosity. Even a small amount can cause vomiting or diarrhea.
 Pet Poison Helpline’s database notes that ingestion of eucalyptus leaves can lead to drooling, loss of balance, and low blood pressure in dogs.
Better alternative plants: Spider Plant, Boston Fern, Areca Palm — all non-toxic to pets.

Eucalyptus Candles, Sprays, and Cleaners
Home products often hide eucalyptus in unexpected places — like laundry fresheners, floor cleaners, and candles. Although they smell wonderful, they can release toxic vapors or leave residue on surfaces your dog licks.
Veterinarians advise checking labels for essential oils and keeping pets away until surfaces dry completely.
What to do: Opt for unscented or pet-labeled products made with natural ingredients like baking soda or apple-cider vinegar.
How Much Eucalyptus Is Toxic to Dogs?
There’s no universal safe dose because each dog’s sensitivity and size vary. Ingestion of just a few drops of oil or one leaf can cause mild to moderate symptoms.
Eucalyptol can trigger vomiting, depression, and loss of coordination within minutes.
If you suspect your dog ingested or inhaled eucalyptus, call your vet immediately and contact ASPCA Animal Poison Control at (888) 426-4435.
Symptoms of Eucalyptus Toxicity in Dogs
Watch for the following warning signs after exposure to eucalyptus:
- Vomiting or diarrhea
- Drooling or foaming at the mouth
- Muscle tremors or shaking
- Unsteady walking (ataxia)
- Low body temperature
- Difficulty breathing
Symptoms may appear within minutes and require immediate care to avoid organ damage.
What to Do If Your Dog Is Exposed to Eucalyptus
- Move your dog to fresh air immediately. Ventilate the area.
- Remove residue from fur or skin with mild soap and water.
- Do not induce vomiting unless your vet specifically tells you to.
- Call your vet or a pet poison helpline with details about the product and amount involved.
- Bring the label to the clinic so the vet can identify ingredients and treat accordingly.
