        Risks related to topical application:

        If you don’t properly dilute essential oils before topical application, they can cause burning, irritation, and hair loss. You should only use 3-4 drops of oil in combination with an ounce of carrier oil. Consult with a vet first to ensure the oil you wish to use is safe, and then make sure you apply it in an area your pet can’t reach.

        Dangers related to digestion:

        Essential oils are never safe to ingest. This is because of how potent they are. Digestion of any essential oil can create severe stomach problems, or even be fatally toxic. Always make sure you keep oils out of reach from your pet, and never take any advice that tells you it is okay to add them to your pet’s food or water.
