Hi everyone. My name is Aimee and our baby is Luna. We have had Luna(yorkiepoo) since November and have loved every minute of it. Recently, Luna went into her first heat. Since then she has been loosing hair on her back end. The vet as well as a breeder we know said it was normal for hair loss around their first and possibly second heat. We were told by another breeder that they would not loose their coats. Can anyone tell me if this is normal? Thanks, Aimee
