Kimbob--Where is the recipe for the pumpkin-peanut butter treats? It might be fun to try, and I do have a cookie cutter somewhere.
I used to bake treats for my sister's dog, but he had some health issues that required a specialized diet. That recipe was complicated (cooked black beans, brewers yeast). I've not baked for our dog, per se, but my husband is always sharing his bread, etc. with her, so in a way, I have baked for her.
