I have a 14 month old Australian Shepard named Sam. He is my buddy. But I have never seen a dog be so destructive. He chews everything to pieces. Came home and he had destroyed 2 new water hoses, one was in 17 pieces. He destroyed the trampoline, the porch swing, the kids playhouse, and the list goes on and on. I know Aussies are bad about this but will he get better? Any tips? I have had him for 13 months and he just gets worse. He is not left alone all that often and is in the house when we are home. He sleeps in the house. Any help would be appreciated.
