Massey is always just up the trail, patrolling the unexplored. I catch this pose a lot as I trudge along behind--ears perked, head tipped, searching for the source of a noise or a scent.
I think if she could flap those ears, she might be able to take off.
One of the best parts of hiking with Massey is simply watching her. She's pretty funny...always has to be in front, goes into huntress mode all the time, and will suddenly dart off into the brush after birds or bunnies or who knows what. Those darts almost always start with the tilt of the head and a curious look.
