my GF 11 month old boxer pup is driving us crazy!!!!!1 she has destroyed 3 plastic kennel pans in the last 2 weeks. she has atleast 4-5 toys in there with her during the day ranging from knuckel bones to sweaky toys. she gets plenty of walking before her time in the kennel when we go to work and is out from the time we get home till we go to bed playing with my dog. so im hoping we are wearing her out to get rid of some energy. what would you guys/gals suggest to keep her from eating the kennel pan?
