Just started both Chihuahuas on Orijen; my cats have been on it for about a month. I can't say enough great things about it as my Chihuahua's allergy symptoms have started to go away, and my cats have lost much un-needed weight. I love how the ingredients are local and how close their formulations are to raw foods. Best of all, it is grain-free. IMHO nothing should be eating grains; I have horses as well and we are seeing many insulin-resistant horses...and most of them are fed grains.
One of the best foods out there, if not THE best.
