I have had her since she was 2 weeks old. Never been outside since 2 weeks. She is now about 7 months old. Eats Henry healthy blocks. Veggies and 1 fruit daily. Limited nuts. She has slowly been loosing the fur on her back right leg. I noticed a small area around front leg that looks like fur is getting thin. It doesn’t look like mange or inflamed. Just like she wore the fur off but it is scaring me. I got calcium in case it was that but she won’t eat food with it in there. She is very picky. Is this mites? Is it a spring molt?
