I noticed that my 8 year old DLH has some hair loss and thinning hair. She has a baldish spot on her neck, thinning hair near her tail and on her neck, and an almost bald spot in the corner of her eye. I'll call tomorrow to make and appointment, but my next day off isn't until Thursday so I won't be able to go til then. Any ideas what can cause hair loss? She isn't over grooming, and the skin below the hair loss is not red or irritated at all.
