Who else is baking dog biscuits? I've been replacing store bought with home made just recently. I met a woman at a Farmers Market that was selling Banana Biscotti and peanut butter hearts that the dogs really seemed to like, and after the market season waned I did a Google search and found the recipes that she was using. After cooking a couple of batches I started just using what I had on hand and the dogs don't seem to mind the lack of a formal recipe! This latest batch is whole wheat flower, rolled oats, milk powder, eggs and peanut butter, with a bit of baking powder and oil.
