[Gracie2006]

Gracie has two Kongs, the little puppy kong and another log-type with grooves in the side where you put the treat. She pretty much ignores both of them. I tried the puppy kong filling, she got that out within 2 seconds. The peanut butter lasts longer, especially in the puppy kong. Even that occupies her for less than 15 minutes. The thing I don't like about the regular kongs is they are hard to clean, and if you forget to clean one, well, it can be rather gross!
