I see this dog on all sorts of breed things and websites as both breeds. Petsmart was also selling a chihuahua mug with this picture on it. Aha here it is: http://www.web-dvm.net/papillon.jpg http://free-extras.com/images/papillon_dog-12576.htm http://wooftown.com/breeds/papillon/ http://www.allsmalldogbreeds.com/papillon.html I've honestly looked at it so much I've confused myself. If it's a pap, the ears are small and head seems large in proportion to the body. But the expression doesn't seem chi to me and the ears are really rounded for a chi. I honestly don't know. You'd think I'd be able to pick out my own breed. Poor dog must be confused. I think the overall proportions look more chi.
