My 3 year old male GSD has some sort of allergies. Not sure what he is allergic to. We have had him since 8 weeks old. We put him on grain free food, no chicken, corn, etc. We have tried gluten free food. We have tried raw diet (hamburg, hard boiled eggs with shells, dynovite, omega 3 oils). Nothing has worked. He does have high volume of yeast. His groin area is black, armpits thick and scaley, and feet and armpits smell like frito corn chips. We give him benadryll twice a day for the itching but he still scratches like crazy. Would Aloquel be helpful for him? Is there any help for him? He just seems so miserable.
