jack doesnt do this, think he does the wide mouth thing, hard to tell tho is it a pant or a smile :P

dogs even laugh :P talked about this at uni today, documented that dogs laugh during play with other dogs, but not known if they do whilst playing with humans. interesting tho

Awww, they're gorgeous. Especially the one in the jacket - my pup has that same maniacal grin when you rub her belly, or when she's playing with her basket ball.
