Hi! We just got our sheltie puppies yesterday. He didn't come from the best breeder. He has fleas and ticks all over him. We saw the mother and father and the father was long haired and the mother was short haired but her parents were both long haired. The breeder also said that someone told her that it could take two years for the female to grow her coat. Our puppy who is 9 weeks today is short haired. We would really like to know if hopefully his coat will grow out?
