My 7 Mo. old GSD had red bumps & spots of hair loss. The vet gave me antihistimine pills that did nothing for her. A friend told me to try taking her off dog food with chicken as a main ingrediant. After a week all red bumps were gone and her fur came back in nicely a short time later. It's hard finding chicken free dog food. Ive been feeding her Taste of the wild lamb & wild rice, but she's getting tired of it and I have to put on a little bacon greese to get her to eat it. Surfing the web looking for a good alternative is really frustrating. The ratings on dog food differ wildly & most have chicken. Does anyone here have a similar problem or able to offer any help?
