What kind of PP work did you do to these? The colors look kinda weird. When you compare the two images it looks like two different dogs because of the colors.
I think the contrast/saturation is stronger in the first shot hence the bolder colours on the dog - I don't know but that shot seems to be a bit softer. As for 2 I like the low angle and the depth of field looks like its in the right place and deep enough to get the whole muzzle in focus - as for the eyes I don't mind them shut as I think that conveys a sense of emotion in the shot.
I like the eyes closed in #2. Very content, very happy, yet attentive, waiting for word from "mommy" or "daddy." Also, the coloration looks a lot more natural then #1.
