Blend all ingredients together in a high-powered blender (I use my Vitamix). Spoon into mold, and freeze for about two hours before popping out of the mold and serving. Keep any treats that are not immediately eaten in a freezer-safe ziplock bag or container for up to three weeks.
Storage: store these 3-ingredient peanut butter dog treats in a freezer-safe container or freezer bag in the freezer for up to three weeks. Serving: These are meant to be served as dog treats fed to your dog occasionally - these are not a substitute for regular dog food. Ingredients: as always, every dog is different and can tolerate different foods. Be sure to speak with your vet if you have any concerns about what your dog can and cannot eat.
