I love it (I love pugs too, we lost ours a few months ago).
I think shinycard's suggestions are good. Though I think this works too, it would make two different photos but both woudl work depending on your preference or the effect you were trying to achieve. I like the high key look here, and the floor in the foreground give the feeling that you are down at the pup's level. I minor distraction for me is the cord under the left paw and the black object in the background. Not major problems though. Nice work.
