I'm new to this so here goes. My silver sable shepherd's armpits are turning black and red. Also underneath his rear end and underneath back legs. He's light colored, kind of beige mixed with black and silver, but very light colored shepherd. Took him to the Vet and she said it's allergies and to put baby powder on them. Didn't work and they're getting worse. He licks them a lot. I feed him Blue Buffalo and always have. He's turning 6 yrs old and never had this problem before and we've always lived in this house. Sure would appreciate any ideas, or should I just take him to another Vet? Thanks,
