yeah she is further along than dd and the skin is blackening and noticed dd is black there too so i was thinking fungal as well - i asked derm about fungal infection for dd down when she was rubbing her vulva and she said it is very rare a dog to get yeast infections in bladder - but i go tomorrow for her recheck so i will ask her about the nose as well to see what her thoughts were. I am glad you posted this as this was another concern of mine as i have noticed it has gotten worse in last six months as i look at pics and then look at her now and i see a difference so it bums me out
before doing the biopsy i would on the next blood draw do the vitamin panel and see if she is low on zinc - I think the vitamin b more has to do with pigmentation than hair loss
