I went to the pet store and found this: http://www.chewy.com/dog/orijen-adult-grain-free-dry-dog-food/dp/29726
I paid a lot less than that. No wonder the shipping is free.
May be worth your while. Logically good nutrition will help dogs be healthier too. Most more diligent people than me will have realized this, of course, but my big AHA was realizing that just because the manufacturer says it provides a balanced diet, and the vet agrees, is no different than the labels on Grape-Nuts and the approval of a medical doctor.
Money talks and bullshit walks.
