Beware, and read the smallprint!
This product contains chicken meal (a very cheap to come by filler, by the way). A lot of dogs have an intolerance to chicken. On the product description It lists Bison and Venison. The chicken is only mentioned when you click 'ingredients'. Many people just trust what's mentioned in product overviews and don't bother with the small print. A lesson learned as far as I am concerned. They should have allergy warnings on dog food like they do on packaging for human food.
