Combine all the ingredients in a medium bowl and mix well.
Spoon the mixture into homemade popsicle molds and top them with a dog biscuit "popsicle stick" if using. I had to cut one end off of each of my dog biscuits to make them fit.
Freeze for 6 hours or overnight. To release the pupsicles, just run the popsicle mold under warm water for a few seconds until the pupsicle slides out easily.
