Last one is the best for me. In shots like the second one, I would suggest that in the future, you probably don't want to cut off its front legs. The first one is okay cut off just at the neck region as it is a head shot, but cropping off ankles and feet (and tail parts too) detracts from the image.
I would also like to suggest that you number your images when posting more than one or two as this makes it easier for a reviewer to refer to an image by number. Numbered images are more likely to get comments.
