Ok, i know people may get tired of hearing this, SORRY! but i just got Bella from a lady who couldnt keep her anymore and she was feeding her Purina Beneful Original Mix. She is almost 4. I read alot and wanted to try and switch her over to Wellness. Just wondering if anyone has suggestions on which one to start with.. Like Wellness Core, or Wellness Small Breed Super5Mix.. Im REALLY new to the dog scene and had no idea that they had these kinds of dog food. I was cluless and thought they only had what was at Walmart. :P Please, any suggestions and feedback would be greatly appreciated.
