Cleaning the Cutters - You want to clean your dog cookie cutters as soon as your dog biscuits are in the oven. Using warm water and mild soap is usually all you'll need. Once they are washed, place them on a clean baking sheet and pop them into the oven for a couple minutes. This will help them to dry completely and avoid rust. Once they are cooled, they can be stored.
There are a couple ways that you can do this recipe to make it more fun and interesting for you and your dog. You can either cook the meat and rice/lentils/quinoa up in a pot with water and add the vegetables near the end of cooking. The other option is to cook the rice/lentils/quinoa and vegetables until soft, mix everything together with the raw beef and form them into meatballs. Cook meatballs at 400 degrees for about 45 minutes, or until fully cooked.
