Thanks for the king kong idea haven't heard of them but am willing to try anything now they still chew on each other fact the male Chinook is always wet around his ears and neck from Foxy I sometimes miss the small fishing village I am from where the dogs pretty much run free and wild I took Nannook there last summer he died less than two weeks after we got back he really didn't like being in a fenced yard anymore he missed running which I know he had been doing at night, I won't be taking Foxy & Chinook there we will have to settle on short trips to Homer if any of you get to Alaska look me up
