A: Tail docking of some breeds may be based on a belief that their non-working members experience risks similar to working dogs; more commonly, however, it is to conform to a distinctive breed appearance or standard. Survey data indicate that preventive tail docking of pet dogs is unnecessary.18,21 Therefore tail docking of non-working dogs, even if their breed was originally developed for working purposes, is considered a cosmetic procedure unless evidence exists to the contrary. In countries such as the United Kingdom where tail docking is legally prohibited (with a few exemptions) the breed standards of traditionally docked breeds have been amended.22
Q: Do dogs need to have tails?
A: It is natural for most dogs to have tails based upon their descent from a tailed species. However there is no strong evidence that naturally bobbed or surgically docked dogs are physically or psychologically disadvantaged. There is some early, but inconclusive, data that raises questions as to whether docking impairs communication with other dogs23 or may increase the risk of developing incontinence.24
Q: Is tail docking painful?
A: Tail docking is painful.25 The intensity or duration of the pain under ideal or typical circumstances is difficult to quantify. Painful procedures conducted in the neonatal period when the nervous system is vulnerable can result in negative long-term changes which affect how pain is processed and perceived later in life.26,27
Q: Why does AVMA policy oppose cosmetic tail docking?
A: The essential question is not “How harmful is the procedure?”, but rather “Is there sufficient justification for performing it?” Performing a surgical procedure for cosmetic purposes (i.e., for the sake of appearance) implies the procedure is not medically indicated. Because dogs have not been shown to derive self-esteem or pride in appearance from having their tails docked (common reasons for performing cosmetic procedures on people), there is no obvious benefit to our patients in performing this procedure. The only benefit that appears to be derived from cosmetic tail docking of dogs is the owner’s impression of a pleasing appearance. In the opinion of the AVMA, this is insufficient justification for performing a surgical procedure.
Q: What forms of tail removal would not be considered cosmetic?
A: The naturally bobbed animal is not considered “docked.” Bobbed genetics exist in many pedigreed breeds (e.g., Old English Sheepdog, Australian Shepherd17) and have been introduced into others (e.g., Boxer28). Some breeders, both historically and currently, would prefer problematic conformation to be corrected via breeding alone.
Removal of a dog’s tail for medical reasons is not referred to as “docking.” The most common reason for amputation or partial amputation of a dog’s tail is traumatic injury where repair of the entire tail is not possible or advisable. Amputation may also occur in the case of tail deformities that negatively impact a dog’s function or increase risk of injury. An argument might be made for removal of the tail of a dog on the basis of repeated prior injury.
Precautionary removal of the tail of a young puppy needs to be based on compelling evidence that the animal is at high risk of tail trauma due to congenital defect, breed and/or planned working activity. However, such a justification must be supported by evidence such as empirical data or impartial expert opinion based on extensive, directly relevant experience.
