PC Nutrition First Sensitive Skin and Stomach

Bought it as the original food was pn back order at the pet store.... cannot find any online reviews for this food though.
Dogs love it and they are tolerating well. Some reason or another our pitty is so sensitive to other foods, and breaks out in rashes and itch.
This food has been good. Just wish it was a higher protien as it is a 22%; compared to our original Nutrience with Salmon 30%. Does have a higher fibre content of 6.5%, copared to the 4% in Nutrience. But it is Lamb vs. Salmon. Vet recommended we change to a higher fibre content as she felt our dog was a little above weight. We are an active family and free feed our animals.
