Stedman is 4 lbs although he THINKS he is a dang German Sheppard
He LOVES to play rough - so rough that sometimes we actually have to pick him up and calm his little butt down because he gets a little too excited and we are sometimes afraid that he may end up hurting himself.
We do play "rough" tug of war with him though - he YANKS and YANKS at his toys and shakes his head from side to side like nobodies business lol - and he does his little "growl" like he is some big macho thing
It is actually pretty funny
He also hauls butt through the backyard with the other 2 dogs who are much bigger than him I might add....he THINKS he is alot bigger than he is
P.S.- He is a cuddler too!
