What You Should Know About Tea Tree Oil Toxicity in Dogs and Cats

Use Oil With Care

Here is the moral of the story: It is imperative to be extremely cautious when treating your pet with tea tree oil (or, for that matter, any over-the-counter remedy or medication). To be safe, follow these precautions:

  • First and foremost, obtain the go-ahead from your veterinarian.
  • Never administer tea tree oil orally.
  • Be sure to check that the product you are applying to your pet’s skin has been diluted to .1 to 1 percent strength. Most over-the-counter tea tree oil is sold as an undiluted, 100 percent concentration. In Australia, 100 percent tea tree oil requires distinctive, child-resistant packaging with a safety warning. No such precautions are required in the United States or Canada.

If you treat one of your pets with tea tree oil and suspect you are observing an adverse reaction, contact your veterinarian or a pet emergency care facility right away. As with any toxicity, the sooner your pet is treated, the better the outcome is likely to be.
