I am looking for a quality food to feed my puppy that will be coming home shortly. I do know to add it slowly, mixing it with what she is being fed currently. I am having a really difficult time deciding on a brand. I want something that is relatively easy to pick up...say at a local PetSmart or PetCo store. I was looking into the Blue Buffalo, but came across a lot of reports of pets having problems with it, kidney failure, etc. I was wondering about the Wellness Core dog food. Has anyone tried that? Does anyone have any recommendations. I have read a few previous threads, but it seems that a lot of the recommendations aren't anything that I've seen locally. Thanks for your help!
