Hi, I recently switched my Cookie from Nutro Ultra Puppy to Natural Balance Chicken Formula and have been VERY dissapointed with the Natural Balance. She has several health problems including demodetic mange and I have been reading about Canidae being good for sking problems. I was wondering if anyone knew of any Canidae retailers in Massachusetts or nearby. I would really like to try her on the Canidae. Otherwise I am open to suggestions about what people have found is good for skin and immune system problems. She is 9 months old now! Thanks!
