52 Essential Oils Bad for Dogs

Share with fellow dog lovers!

Essential oils are a popular way to provide natural fragrance in your house–but they have to be used with caution in pet households. If you are wondering which essential oils are bad for dogs (and for cats, if you share your home with felines, too), please note that many essential oils can be toxic to pets, even when they’re not being used directly on the animal. We’ve got veterinary advice on use of essential oils in your home–and 52 essential oils to avoid.

This guest post from the Texas A&M University College of Veterinary Medicine & Biomedical Sciences is important to read if you use essential oils in scenting your house, cleaning your house or for your own health.

Essential Oils Toxic to Pets

Essential oils are often presented as a naturalistic approach to personal care and home fragrance. However, just because these oils are derived from plants doesn’t make them healthy, or even safe, for your pets.

Dr. Murl Bailey, a professor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences (CVM), advises pet owners to use essential oils with caution.

Special Danger of Diffusers to Cats

DogTipper Tip: Beware of diffusers around your dog as well as your cat. While cats are at special risk because of self-grooming, dogs also lick their paws and can ingest the toxic essential oils that have accumulated there.

When essential oils are used in fragrance diffusers, the oils are widely distributed within a room. Because many of the oils commonly purchased in stores can be toxic to cats, if a cat breathes in a harmful oil, it may cause respiratory irritation.

“Diffused oils are very dangerous, as the oils are inhaled,” Bailey said. “Not only are these oil droplets dangerous themselves, but the inhalation of these oils can cause a foreign body pneumonia in cats.”

Some diffusers, which act by aerosolizing the oil, release micro-droplets into the air that may collect on the fur of a pet cat.

When the cat grooms itself, the oil may be ingested. Symptoms of respiratory irritation include a watery nose and eyes, drooling, vomiting, and difficulty breathing.

In cats, difficulty breathing may be mistaken for the animal trying to expel a hairball. Difficulty breathing can be distinguished by the cat crouching low to the ground with little abdominal movement and no hairball production.

If a cat owner suspects that their pet is in distress, they should move their cat to fresh air immediately. If the cat does not quickly recover, the owner should seek emergency veterinary care.

For any instances of poisoning, owners can also call the Pet Poison Helpline at 855-764-7661 or the ASPCA Animal Poison Control Center at 888-426-4435.

Essential oil diffusers also pose the hazard of tipping over. If this happens, there is the possibility that a cat might ingest spilled oils, which Bailey warns against.

Ingestion of Essential Oils

Essential oils should never be given by mouth or in the animal’s food,” Bailey said.

“Oral ingestion can cause vomiting, diarrhea, and central nervous system depression, which can cause symptoms such as decreased heart and breathing rates. Seizures are also possible from large doses.”
