One of my dogs inhaled his tonight (it's his birthday treat). The other one is taking forever to eat his -- it's like he's savoring every lick. Birthday boy is sitting there eyeing him carefully. They seem to prefer peanut butter flavor to plain, but then, who can tell really?
I have two very happy pups tonight!

OMG! I just found a recipe for making our own. This will be much less expensive.
Frosty Paws Dog Ice Cream
32 oz vanilla yogurt
1 mashed banana or one large jar of banana baby food
2 T. peanut butter
2 T honey
Blend all together and freeze in paper cups. Peel away the cups & place in your pets dish to serve. These can also be made in a non-salt automatic ice cream maker and served like regular ice cream in a dish.
DO NOT freeze in ice cube trays as your dog is likely to eat them so fast he’ll choke!
