I sort of know how you feel. When we went to pick Indie up as an 8 week old, the mother to the other litter had a full tail, and man-alive it hurt when we were in the firing line! Indie has a docked tail, she is fine it that. The breeder mention how having a tail can sometime led to no good for them, as they make them bleed and in some cases break them (painful). The only thing advise I can give is wrap it in bubble wrap, when they hit, it won't hurt and then the other 50% of their time will be spent on trying to take it off! haha just a thought.
anything to keep them busy.
