puppy chewing was a problem with Gracie. we went through so many toys it was crazy! a Kong full of peanut butter fianlly conquered the chewing. she destroys all her toys, but she's had this Kong since she was 9 weeks old. she's actually playing with it right now. chewing wasn't a problem with Jake. the ONLY thing he chewed other than his toys was THE WALL! fortinatly the kong came to the rescue once more and Jake would chew on the Kong instead of the wall.
