I got this food for my English Springer Spaniel.  He always provides a litmus test for dog foods.  He has severe food allergies and gets bad reactions to (almost) any food that is not grain-free.  Even some grain-free choices have caused rashes and itching.  So far he has done very well on this food.  He also likes the taste and shows other signs of good health (although it's admittedly hard to tell much difference after one small bag).  I always stop on over to DogFoodAdvisor and see what they have to say.  This food scores pretty high, a rare 4.5 stars out of 5, putting it up there with the most expensive grain-free foods (obviously where it belongs!).  The main ingredient is lamb, followed by other high-protein ingredients.  There are very few "bad" ingredients.
