Dog Food Manufacturers in Health and Genetics Posted December 2, 2010 · Report reply We feed the KIrkland foods to our four dogs. With the exception of Ginger just being diagnosed with Valley Fever, they are all doing very well. Our husky is going to be 10 and he certainly looks and acts much younger. With four dogs we just had to stop feeding the super premium foods once the price started to rise so steeply. I did call Diamond and Costco before we started feeding it and I did get a lot of good answers, unfortunately I'm not exactly sure what the info is anymore! It took quite a few phone calls. I'm almost positive that I posted it in a thread somewhere on here a long time ago. I'll see if I can find the old thread.
