My dog Ava has been getting bald spots around her head, neck, a little on her back close to her head, and one on her paw. It is not oozing out any liquids but it is really pink/red where the hair has fallen out. The skin looks a little scaly at times. I don't know if it spreds or new spots just start. Ava is a little over 6 months, she's a full breed American Pitbull Terrier. I am getting an appointment with the vet tomorrow but they usually take a day or two to get you in, so for now I want to see if anyone has advice. Please help! Thank you.
