I have never made treats for the dogs to eat, but when the kids were younger I had a home-made Play Doh recipe that we used to make ornaments for the tree. We used cookie cutters and cut out bone shapes, etc. and then put the dog's name on them. We also made free hand shapes of our dogs and, since we had poodles, we would use a garlic press to create "curly fur" to put on our dogs. Then we baked and painted them and put on a glaze.
