I think people are fooled by thinking it looks more like a pom than a chow or akita pup because of the shaven fur on those chow/pom mixes picture in the OP. the fur would be the same across it's full body almost and appear much larger.
Not saying it's not a pom because it is mixed with one apparently, im just justifying why one might think otherwise.
poms have such tiny little legs and bodies though and the one in the OP looks like it's pretty thick, even without the fur. (thats the chow in it--however could have been easily mistaken as a japanese akita)
