They banned docking in many breeds in Europe. They said it was cruel but then many dogs had tramatic injurys that were normally docked and so they had to have it done later in life. WHY? because there was a reason they had them docked as pups later on they had the same thing happen as yours.. injury! SO they had to have thier tails amputated. Docking IMO is the same as a lil boy being circumsized (sp) they do it when they are to young( a few days old) to remember they have no bones( it's like your ear before the bone hardens) hence why vets will only do it a right after birth. It prevents pain later in life due to injury. Call around,, ask questions,, explain the situation. Many pitts are docked . It won't hurt him if anything it will help.. no more infections /pain!.. I have boxers and let me tell you had they not had thier tails done I would be in this same situation.. injured tails! Let me tell you that lil nubby can shake like a frieght train!
