Let me get this straight, you basically took a poorly composed picture of a dog's a$$ and you expect to get positive comments? And if that's not amazing enough, people are saying "nice shot"?
Haha! It is a fun pic, but would benefit from being shot from the front where we could really see his/her snout buried in the snow.
This lover of dogs enjoys the playfulness of the shot, but it's unfortunately got his/her hiney as a bullseye for drawing my eye.
I do understand that this is a quick grab though, and with all the movement, sometimes we just "gets what we gets." My experience with my playful Lab nets about 1 keeper for every 20 snaps if I'm lucky!
