Humans aren't the only beings that like frozen treats. Dogs do too.
Ingredients
1C organic pumpkin
1C greek yogurt
1C peanut butter
(make sure none of those things have xylitol, it is deadly for dogs).
Directions
Mix well - I used an immersion blender but you can do it by hand. Put in ice cube trays, about a quarter of the way full in each. Freeze for 24 hours.
My dogs go nuts for these.
