Why eucalyptus is toxic to dogs

The plant contains aromatic essential oils. Eating a little of the fresh plant usually causes only stomach upset. Concentrated essential oils are far more potent and are absorbed through the skin and lungs as well as the gut.

What to do if your dog ate eucalyptus

Remove plant pieces from your dog's mouth and move dogs away from the plant. Wipe sap or pollen off the fur and paws with a damp cloth.
Call your vet or animal poison control for advice: ASPCA Animal Poison Control: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661.
Identify the plant. Take a photo or bring a piece (or the plant label) to the vet, and estimate how much was eaten and when.
Do not make your dog vomit unless a vet tells you to. Home remedies such as hydrogen peroxide or salt can cause serious harm.
Watch for drooling, vomiting, diarrhea. Go to a vet if signs are severe, last more than a day, or your dog has trouble breathing or swallowing.

Treatment and outlook

For the plant, supportive care is usually enough. For essential oil exposure, wash oil off the skin with dish soap, do not induce vomiting (oils can be inhaled into the lungs), and call your vet or poison control.

How to keep your dog away from eucalyptus

Place eucalyptus on high shelves or in hanging planters out of reach of paws and tails, or in a room your dog cannot enter.
Give your dog something better to chew: chew toys and puzzle feeders reduce boredom chewing.
Pick up fallen leaves, petals and pollen promptly, and empty vases where pets can reach them.
