The base for most bitter apple sprays is apple cider vinegar. This vinegar has a tart taste that most dogs stay away from, making it a perfect repellent.Mixing three-parts cold water with one-part white vinegar in a spray bottle creates an effective solution that can help take puppy stains out of carpeting as well as discourage chewing and urinating. White vinegar is a natural disinfectant and a natural deodorizer as well. The vinegar scent will disappear within a few minutes after use and take other odors along with it. Dogs have sensitive noses, however, and they can still detect it and will generally stay away from it because it bothers their noses. The water and vinegar solution is completely non-toxic and 100 percent safe around kids and pets. Some people prefer this method because there is no alcohol in it. It is used the same way as Bitter Apple or Listerine. Just spray the mixture on items that are not supposed to be chewed and see if it is effective for your dog.Bitter Apple has been a popular dog-training device and chew deterrent since 1960. It normally comes in a spray form, and while the smell can't be detected by humans, both the taste and the smell are harsh to dogs. It is non-toxic and won't stain carpet or fabric so it is frequently used as an anti-chew device. By spraying Bitter Apple on items in your home such as shoes or furniture, your dog is discouraged from chewing on them.
