My Dobe LOVES squeaky toys. If she doesn't have something to chew on, she'll chew on me (lol). We've tried the Tuffy brand and she ripped it to pieces, though it was only a lvl 8 on the "tuffnes" scale. (It did last longer than most toys I'll admit). The Sherpa Go Dog Plush Dragon was suggested to me by a friend whose dog can tear through the red brand of Kong. This toy lasted a maximum of 20 minutes before there was hole in it. Any other suggestions?
