Dude; you're ticking me off!
Freezing time at the exact moment of full expression is a hit and miss type of thing. I'm always looking for "the look," but often I miss it. When I've seen it but didn't capture it; I'm ticked off.
So much can be read into a canine facial expression; sometimes what we see is simply soft and angelic. Other faces are just funny; calling out for a one liner. While many "faces" are just too cute for words; the ones that stir emotion in us just at a glance. Awwwwwwwww; how cute is that face? Honestly you would swear that some dogs are just trying to be cuter than belief.
"This is disgusting;" gag looks are common.
I almost always catch the big bored yawn. Right in the middle of the shoot; yep being a photo model is one tough job.
There are the smiling faces; just happy to be.
I'm a little shy but would love you to throw my ball.
Then there are the tiny sleepy faces. These ones don't need any work to be adorable; they are just as adorable as can be all on their own.
