Thanks guys! I think they are pretty cute too but I'm a little biased :P
And more like its sweet how he gets beaten and mauled by the chis haha. They hit him in the face and nip him for taking "their" toys (his own that they stole) and he just takes it all in stride. I don't even think he feels it haha. He is very gentle with them for a puppy but of course play has to be supervised very closely as his feet are bigger then their heads!
