When my dog Louis would look up at me with those sweet puppy dog eyes, I always called them his "Moon Eyes. The bottom of the whites of his eyes would show, and it looked like a moon. So for me, this charm is a sweet representation of Louis. I wear this sweet charm stacked with my other charms. What does a moon represent for you?
