our poor pups are SO sensitive to food... make sure you put her on a human grade food... only 100% natural.. with no chicken (you'd be surprised how many pups are allergic to chicken!) no wheat or corn.. layla's skin in a MESS!! we just switched to Fromms but i know that Canidae and Wellness are GREAT foods... you can try adding Omega 3 oils to her diet (open a fish oil capsule on some wet food for her) we've come to the end of our rope with the dry skin.. and Kathryn_V sells a shampo that everyone on here just RAVES about so we just ordered some tongiht
good luck!
