Is Clove Oil Safe for Dogs?
Why it’s a problem
Clove oil is rich in eugenol, a phenol that burns mucous membranes and can depress the nervous system. In dogs, swallowing concentrated oil causes gastrointestinal injury, and larger amounts stress the liver. Diluted clove products still carry risk because dogs lick whatever is on their coat.
How to keep your pet safe
Never apply clove oil to a dog, including on the gums for toothache, and keep bottles out of reach. Brief, passive diffusion in a ventilated room is lower risk, but skip it around dogs with airway disease. Use veterinarian-approved dental care instead.
Warning signs to watch for
Drooling, pawing at the mouth, vomiting, diarrhea, weakness or wobbliness from low blood sugar, lethargy
When to call the vet
Call your veterinarian or a pet poison hotline if your dog swallowed clove oil or got it on skin. Do not induce vomiting unless directed, and mention how concentrated the product was.
Common questions
Can clove oil be used for my dog’s bad tooth?
No. Applying it to the gums can burn tissue and be swallowed in significant amounts. See a veterinarian for dental pain, since it usually needs treatment, not just numbing.
Is clove oil safe for dogs as a mosquito repellent?
Not recommended. Dogs groom their coats and can ingest eugenol, and concentrated oil irritates skin. Ask your veterinarian for a pet-safe repellent.
