My Frances appears have hair loss on her flanks and her back. As I have been doing research I can understand her flanks being SFA but could it be the same for her back too? She is going to be two years old this August of 2018. In spring of 2017 she was having extreme hair loss as well , I was given antibiotic pills and antibacterial and anti fungal shampoo from the vet. The antibiotic pills did not really do much hair kept falling out but shampoo bath every 10 days did help. This year not so much. The vet did mention last year maybe it was her pup coat and winter shedding away all at the same time. After a few months she got better by end of 2017. Though this 2018 spring here we are, unlike 2017 she now has missing hair patches on her flanks and her back. On her flanks the hair is missing with black pigmentation and no black pigmentation for her back but missing hair patches with a lot dandruff on her back. Also noticed the hair in her white face easily falls off if slightly pulled. Side note like face hair, her shoulder hair was falling out as well but has stopped after a few weeks and now appears to be normal. Don't know what to think took her to the vet he was baffled. I was requesting a scrape but he said it was not mange so he didn't think it warranted it. Really need some insight.
