I'm sure others are going to say that you shouldn't have cut the tongue off!!! But I won't. I like the way this shot is framed and I like the angle of the dog's head in diagonal through the photo
I really like the cropping around the head, but the fact that the toungue is cut off and a little out of the focal plane bother me a bit. I do like, though, how the body of the dog is slightly out of focus. The texture and detail you've managed to capture in his/her fur it really nice.
