Hi scottny,
Why does it have to be a cookie type treat? I make jerky treats for my dogs using free-range chickens and wild caught fish. They are 100% meat or fish which is much more appropriate for a dog than a cookie type treat. They will give the stomach acid something to work on to help with the regurgitation issues. Dogs absolutely love all meat jerky treats. Chicken is the most universally liked dog treat I have ever seen!
A simple recipe is use any fish fillet or chicken breast or piece of meat that has no external fat. Slice thinly, turn oven on lowest setting. Place on cookie sheet and if possible leave the oven door slightly ajar to let the moisture out and bake until treat is able to be broken in half by bending.
