Dog photo - vignette or no?

I am pro vignette as well. I think it might look good with a square crop too, though I am kinda weird like that. A photo like this where the only point of interest is the symmetrical subject really needs to be perfectly centered. If the dog was looking to the left or right that would merit looking at non centered crops.

First photo with the vignette for me!

I like both, but the centered with vignette is my favorite.
