My present dog, a Lab, was introduced to Pedigree at puppy stage, but never really liked it. We tried most and now she thrives on "Mimaskot" and has done for the last four years. We do a little home cooking for her as an addative, but she is a one a day dog and flourishes very well on it.
Our previous dog was simular. Started on Pedigree but would only eat "Topitop" Cheapest of the cheap.
