I have a five month old Merle great dane pup named Radio, he is already the size of our two year old Lab and is worse than Marley and me. So far he has destroyed a wii, ate a hole in our chair ate a stereo up, mutilated our blinds, and ate countless dvds, oh and destroyed some dryer sheets, and some of my little girls toys :(. we have our house sectioned off where at night the dogs have there own room and can go in and outside whenever they would like into our fenced in yard. We have a door that leads that room into the other areas of the house that we keep open during the day. He has his own toys, and everything but still massacres anything within his reach. What would be a good way to train him or an indestructible toy that will keep his attention and keep him away from the other items in his reach, or is the only way to keep things safe is to put him in a completely empty room. Ive been told to try Kong balls with like peanut butter in them any chance this will work.
