Yup, it's a dog all right.  I like the angle from which you shot it but, the down side, I also don't like losing the feet.  A bit of a Catch 22.  The dog is set up nicely and has very cute/lively expression.  Ears are UP!  Very good.  Tail is UP.  Also good.
I think I'd like to see the background (is it water?) more out of focus.  And the lighting is a bit harsh.  I'd clone out the dog tag.  Overall, a very nice shot of what appears to be a very nice, happy, alert dog.
