Thanks RD; apparently the toy variety is very popular; everyone who meets him says the same thing . . . "they can be that big?".
Strange; I like his size; he's 21 lbs., 17 inches at the wither; he's a bit "racy", but I have a pup coming in August (hopefully -- the female is pregnant now) that should have a fair bit more bone.
He's freak'n fast though!
