Cindy B. Milwaukee, WI 3/25/2009 9:14:01 AM I have a two year old bulldog mix that has patches of thinning fur on his sides. Our vet said it is thyroid related and put him a meds for treatment. Since he has been on the meds, the patches seem to be bigger. Bully's dander has been very active, it almost looks like dandruff. He's been bathed in medicated shampoo. We are at totally lost as to what is going on. Can anyone help us?
