One of the most controversial subjects in the field of dog training is the question of debarking surgery. Debarking surgery is a procedure designed to minimize the volume of a dogâ€™s bark. It is generally used by those with dogs who have both a loud bark and a tendency to bark incessantly. The procedure is most commonly used on very loud larger dog breeds. Shetlands and collies, for instance, make up a large percentage of those dogs subjected to the surgery.The procedure generally requires the use of a general anesthesia and involves punching, cutting or otherwise manipulating the tissue around a dogâ€™s vocal chords to soften or significantly reduce his ability to bark. Access the areas targeted during the surgery can come either through the dogâ€™s mouth or via an incision on the dogâ€™s neck.
