My poor sweet little 5 month Pembroke smells terrible. It started gradually about a month ago and has gotten worse and now his hair has begun to fall out. I have a one year old female Pembroke who doesn't smell at all and her fur is beautiful. My male keeps having problems and I feel terrible for him. I am taking him to the vet on Tuesday (my third in several months) but I was hoping to have some idea what could cause this before I go. I have had some bad luck with vets. Any ideas?
