You should only use 100 percent pure essential oils for pets and always dilute them before application unless otherwise directed by your veterinarian. How much oil should you use? Recommendations vary, and you should ask your vet if you’re feeling unsure, but a safe bet is starting with a single drop of essential oil in 50 drops of carrier oil, such as coconut, olive or almond oil. Another recommendation is to use three to six drops of essential oil(s) to one ounce of carrier oil.
Of course, it’s important to adjust the amount of oils you use depending on your pet’s size and age. Use less of a diluted oil with smaller dogs and cats, as well as puppies, kittens and senior pets.
To enable your pet to benefit from the scent of essential oils, put one to two drops of essential oil in a diffuser and allow the aroma to permeate the living space for 10 to 15 minutes.
