I've never been around any of those but pits so I can't say anything about their health with tails, but I fully believe that it is completely health for a pit to have its tail and have yet to know one that has had a problem with hurting their tail. Some dogs may need their tail docked for that reason and that is fine, but I know some breeds do it for cosmetic reasons and I don't like that personally. But like I said your opinion is yours, just like mine is mine, and they are all different. I am not against it in the sense that it should be banned as long as it is done correctly and in good clean envirnoments. I heard some do it with with toe nail clippers just like they are cutting toe nails and that to me is wrong.
