Kong is the only toy my pittie didn't kill in 15 minutes.
My Dane didn't like them even filled with peanut butter.
She would destroy a cow femur in a few hours. She had some damn powerful jaws.
In-laws Thai Ridgeback has killed everything we've ever got her. She punctured and chunked out the side of a Kong, and it was over not long after that.
Hell, in his younger days my Corgi would kill everything I got him.
