Blend all ingredients together in a blender.
Pour the mixture into popsicle moulds, paper cups, a cupcake tin or ice cube tray. Freeze for 30-40 minutes.
At this point, the popsicles should be a bit slushy and will hold the dog biscuits in place. Place one biscuit into each mould, with about half of each one sticking out above the mixture.
Freeze for another 3 hours or overnight.
Serve to your pup!
