Bitter Apple Spray can be sprayed on wounds & dressings to deter your pet from licking or chewing. It is also great to stop teething puppies from chewing things they shouldn't, such as furniture or shoes. The spray can be used on cats, dogs & even ferrets, & does not harm the finish on real wood furniture. Directions: Spray directly around the wound or over the dressing, or in the case of furniture directly around the areas that you want to protect. Ingredients: Isopropanol 20%, bitter principles & extractives.
