I'm not prevet or anything just saw the post. The only real time I see it worth doing is if you are dead set on making it a show dog where if you don't you will be disqualified. I have a doberman and never got his ears or tail done, although when I was little my sheepdog did have her tail done. Overall I think it is generally worthless just as the website above says. If one is really into doing it then it MUST be by the proper person. I have seen too many poor dogs that have had idiots butcher their ears so they look meaner or just try to do it themselves to save money. Also the douches that put elastic bands around tails or cut them off with scissors makes me sick...
