Buffy is with me again today. She has a lot of facial expressions. It's tough to capture any of them because she is a little afraid of the camera, since it makes noises. Here are a couple attempts plus an icon
When things aren't quite right Buffy will sometimes curl up her lip on one side into a sneer. Another dog barked at us in the backyard and she came up with this double sneer. Though it looks more like her imitation of a hamster with its cheeks stuffed full!

Here she was yawning or clearing her throat, but she looks like she's playing supervillain!

Finally, here she's just snooping around, and it looked like a good subject for an icon.

I love the icon, it's perfect.
