Rusty really enjoys the small bites. I usually add the dry dog foot to a little canned wet dog food and make it just a little bit warm. He likes it that way and it smells good too. Any bites that accidentally fall on the floor during food preparation quickly disappear.

Love the Product, Wish there was a Larger Bag

My dog is right between small and medium and just isn't into the big pieces. We switched to these small bikes and she has stopped going after the cat food. We love everything about it except the small bag. We'd love a cost-effective bigger bag option.
