you used flash, and there is a very dark shadow of the dog's ear
it seems that the dog has 3 ears... :p
the dog is at rest but his ears are "activated".. they are not lowered down..
you have to be patient with animals (or people too :) to get a better photo, i'm sure if you had waited for a minute or so you could get a perfect "dog at rest" picture
