he looks so tiny and almost fake
i had one exactly like that, when he held still ( which was seldom) he looked like a toy dog.
very playfull . . . i'm hoping this isn't the case with your cutie, but mine use to shit all over the place. nothing seemed to work. he went to the door once to poop that's out of an estimate of 1000 shitting and pissing events . . . even worse, when ever we left him alone for more than five minutes he would make an abnormal cross between a chicken and a dog howling. he would do it till finially some one came to his attention. it drove me nuts.
and he was one horny dog. he had his own great big teddy bear to make sweet love to atleast 5 times a day. it was our way of keepin him off of our feet and legs, it worked wonders.
good luck with the little guy they certainly have amazing personalities,
