Lamb diets

[Thomasina]

Any advice on lamb/rice diets, my girl has Auto immune and has list muscle on her hind legs and a lot of her coat, reading that lamb is good for muscle building.
I'm feeding both dogs a fish grain free diet but one of them is biting her back, bum licking and both dogs are paw licking.
Wondering if it's the fish or no grains that's causing it.

I feed Platinum lamb and rice (not for many particular reason other than I think it is a good food, and my dog likes this flavour).

Adult Lamb + Rice

I'm happy to answer any questions you have, if I can.

Could the cause of the licking be an allergy to something in the environment rather than diet?
