Of course, we all want to know what Boo is like in person. Here's what Gretchen had to say:
"Boo is friendly and easy with strangers and other dogs. Initially he runs around excitedly before settling down for the camera. And he can be overstimulated with wide-open places such as the beach. Boo seems most comfortable in contained, cozy places. One of his unique charms is that he immediately climbs into any cubbyhole spaces that happen to be in a room, such as a bookcase or a console with sections."
