If you have a dog on a prescription diet like K/D..R/D..W/D.. you can make them treats from the can food. Open a new can and slide all of it out still circular. Slice it into thin rings. Place them on a foil cover cookie sheet. Cook in oven on 350 for about 5-10 minutes until top is dry. Turn them over and cook another 5-10 minutes..until dry. You can make them as crunchy as you want and as thick as you want. Dogs love them and are safe for their diet.
