Docking Your Dog's Tail

This procedure is typically done on puppies between 3 and 5 days of age. No anesthetic is involved, and the tails are docked to an appropriate length for the breed. Some of the breeds normally docked include the Rottweiler, Doberman pincer, Boxer, Schnauzer, Miniature pincer, Toy Fox Terrier (amongst other terrier breeds), Corgi, Poodle, and Sckipperke to name a few.
This procedure is much preferred done while the puppies are less than a week of age. Afterwards, the puppy has to wait until it is of age appropriate for anesthesia, which is much more involving a procedure, with a much longer healing process. There is also associated pain with the procedure when done on an older animal, and complications include bleeding, premature stitch removal by the dog, poor healing of the area, and more chances for scarring to occur.
Unless the dog is being utilized for show purposes in the conformation ring, tail docking is best left undone if beyond the age of 5-7 days.
The American Veterinary Medical Association (AVMA) has recently made a statement with regards to cosmetic tail docking in the dog. Essentially, and ultimately the AVMA would like to see this type of cosmetic procedure discontinued for cosmetic purposes only.
