I had such high hopes for the Kong Extreme, but less than 35 minutes after stuffing two Kongs for two different dogs, both toys were emptied and destroyed. I have a 50-pound Boxer/Pit mix (Jasmine) and a 60-pound American Bulldog (Brody) mix. Brody gets credit for destroying most hard toys, while Jasmine takes credit for taking care of all soft toys. I've included a video of Brody quickly destroying the second Kong, hoping it might serve as a reference for others in terms of chewing persistence and strength. Once he figured out how easy it was to remove the top of the first Kong, he used the same strategy for the second and popped it off in less than 90 seconds. If anyone has other suggestions for durable, engaging toys that make smart dogs use his or her mind to solve problems (and be rewarded with treats), I would love to know. I have tried the Starmark toys (both the bob-a-lot and the cube), Busy Buddy Linkables, the Petsafe Buddy Squirrel, and some of the "board games". Because I work from home, I'm looking for something that will quietly preoccupy two high-energy dogs for at least as long as a 12" rawhide stick - 30-90 minutes.
