I just went an picked up my female that was at a friends house for 6 months to be breed to his male. He told me on two occasion he would bring her back because she didn't come in heat. Today I decided not to go to work and go see him. She a little skinny for me. Never had a dog with a open sore in that spot . What's the best way to get it healed and what is best to use to re gro her hair? Thanks
