30 Essential Oils that may NOT be safe for pets

Please be careful when using essential oil diffusers around your dogs.  Essential oils truly do impact your dog's well being.  The following list may cause seizures and even death, especially in smaller dogs. Of course, toxicity depends on level of exposure. At low levels some of the oils are actually beneficial if the exposure levels are kept within the therapeutic limits.  Always follow veterinary guidelines for exposure when using essential oils with your pets.  See below sources for a couple references that we recommend.
