OK, so this one might not be for your dog! But, you should try this out on offensive cat odors.
A light and refreshing blend that completely neutralizes the potent ammonia scent of your cat box. A perfect blend strong enough to mask odor yet light enough that cats will still use their box. We’re not kidding! You will get 3 to 5 times the distance with your litter. The plus side is that lemon and lavender are wonderfully antiseptic. Very clean!
