Kong makes many different products for dogs, but the products I am reviewing are probably their most popular; the treat dispensing toys. These toys come in several different forms: the classic kong, the kong wobbler dog toy, the goody bone, the stuff a ball, but all have a similar premise. These toys are designed so one's pet has to work for their treat. This a great product for when the dog is going to be left for awhile on it's own. The treats keep my do interested in the toy, and the toy makes it difficult enough so that my dog doesn't finish her treat quickly. When using the classic kong, I tend to just fill it up with peanut butter instead of the kong spray. It's actually more difficult for my dog to get out the toy and it's more affordable.
