Before using any oil on your Doggie, simply try holding a bottle of it in your hand with your furry friend friend in the same room. Allow the Doggie to approach the new item, but avoid letting them actually smell the bottle just yet. Remember that Doggies are scent-driven animals and have more acute sense of smell than humans. You don’t want to overwhelm them with too much too fast. If your Doggie seems okay with the scent, you can let them smell from the bottle. Give it a day or two and try it again, then move forward only if everything is okay. At that point, you can diffuse it in a room, adding a couple of drops to a diffuser, but do not apply it directly just yet. Post that you can choose from one of the below mentioned options which have been proven safe for Dogs.
