I am currently feeding California Natural chicken and rice. I have been pleased with the results, but am curious about Healthwise. I need to cut down on some costs and the Healthwise is better priced. Diamond Natural is also an option. As far as quality how would you rate the three? Does anyone have personal experience with Healthwise? I have never fed Diamond, but have been happy with all the Natura products. I just don't know if switching from CN to Healthwise would be a big down grade. I have 60 pound 2 year old golden, pointer mix. Thanks!!
