How I like to use my lavender oil indirectly with my dogs are when washing their dog bed covers. First, I wash my dog bed covers in the washing machine on a cool water gentle cycle. Then I like to air dry them and fluff them in the dryer. Before I close the dryer door, I put about 4 or 5 drops of lavender essential oil on my wool dryer balls, throw them in the dryer with the dog bed sheets and even a favorite sleeping blanket.
