In the Winter Living Magazine, p 11, Dr. Janet Roark , veterinarian with Hill Country Mobile Veterinary Service continues her article with myth busters.
“MYTH: Never Pet your dog or cat after using oils. TRUTH: Petting is actually an excellent way to apply oils topically to pets. Along the spine or on the ear tips are the most common applications. Here is the issue behind this myth: after using oils like Peppermint , Deep Blue; http://bit.ly/2QQ4cFH or others, http://bit.ly/2CyReT5, the oil smell can linger on your hands. I’m sure I’m not the only one that has rubbed my eyes after applying Peppermint- ouch! The same holds true for your pets. Any residue from your hands can have the same effect on them that it would on you. Essential oils are volatile, which means they dissipate into the air rapidly, and they absorb into the skin quickly. This means they won’t stick around for very long. If you are worried though, washing your hands after using oils and prior to petting your pets is an option.”
