Hello, my dog Sophie, is ten months old now. Two months ago she had come into heat for the first time. My mother's dog, which we assumed was her dad, busted a hole through the skirting around the house to get to her. The breeding was completely unintentional. She had six, healthy seeming puppies however, one of them was born with half a tail. I was wondering, with this defect, is there any problems that may go along with it in this puppy's future?
