Stop dog from chewing on stitches?

You can use commercial products like "Bitter Apple," available from your veterinarian or at a local pet store. Some dogs are unphazed by it. You can also try Tabasco, but be careful not to get it close to the wound. In the end, the surest way is to use an Elizabethan collar, which again is available from your veterinarian or pet store. This is a plastic cone that goes around the dog's head and attaches to his collar. Dogs don't like them, so be patient and try to help him have a good experience starting out by giving him treats and praise while wearing the Elizabethan collar.
