Oh my! She's Adorable!

I have a hard time getting a good picture of Blanche. Not because she's not adorable or anything, because obviously she is. But because I can't seem to capture her personality in a still image. It might have something to do with the fact that she is always in motion, always on the move. But also, I think she kind of shuts down when the camera comes out. Many of the pictures I have of her are a blank stare and not the beautiful smile she has.

I happen to get this shot this summer and am really loving it. I feel like it shows off her personality and happiness so much better than others I have. Yes, she is chewing on a pen, but she's happy doing it! Any tips on how to get better candid, happy shots?
