Made with Copaiba oil and other natural ingredients, you can safely apply the spray to household items or skin. Whether youre trying to discourage your dog from chewing your DoggieLawn or licking a hot spot, Rocco & Roxies No Chew Bitter Spray can help pets refrain from gnawing on things they shouldnt. Copaiba oil is a bitter tasting essential oil that deters chewing but also helps soothe irritated skin.
