Sleeper, is hard to describe... he is very big, with arms like tree trunks... around 65lbs and well furred. He reminds me of an expedition dog. He is friendly to the point he knocks you over... I spend time with him every day trying to teah him not to jump, but it really doesnt help much. He is a handful to try and harness because he has a lot of power. On the downside for me, I think this dog will get way too hot in our temperatures down here in Utah which can run very hot in the spring. He's also a little too big for me and I'm trying to stay with smaller dogs these days.
