Plug the side hole of your Toppl with a Stoppl or similar stopper. A thick banana slice or large dollop of Xylitol-free peanut butter will do the trick if you don't have a stopper.
Cut the watermelon into chunks.
If your dog likes watermelon chunks, place a few chunks into the Toppl. If they find watermelon chunks suspect, skip this optional step.
Place remaining watermelon chunks into the blender. Add the light coconut milk. Blend until smooth (just a few seconds really).
Pour the watermelon mixture into the Toppl and freeze.
If used, remove stopper before serving.
