To stop a dog from licking obsessively, eliminating parasites is a possible solution, as fleas, ticks, and mites are among the most common causes for compulsive dog licking, chewing, or scratching behaviors. There are a variety of flea and tick products that your veterinarian can recommend. Additionally, if your dog’s biting or chewing problems are caused by fleas, be sure to wash your dog’s bed and vacuum your carpeting and upholstered furniture on a regular basis to reduce the likelihood of re-infestation. Preventing the behavior is also important, and some ideas include using bitter sprays to discourage licking, having your dog wear a special collar to prevent access to hot spots, or keeping your dog close by your side when you’re home. Addressing anxiety or boredom can also be helpful, by ensuring your dog receives enough exercise, attention, and love, and training your dog to chew on toys or bones to relieve stress as a replacement for inappropriate chewing or licking behaviors. Your veterinarian may prescribe medications to treat underlying problems contributing to your dog’s persistent scratching, and may recommend the use of topical or systemic antibiotics, steroids, or anti-itch products to treat existing hot spots or skin infections. Changing foods can also make a difference, if food allergies are making your dog itch, eliminating potential trigger foods can help. The addition of fatty acid supplements to your pet’s regular food can also help address dry skin issues and keep your dog’s coat healthy.
