I have the same concern as the thread started by sprocket, only it's a pet that I'll have to leave behind when I go on a month-long section hike next summer. I've left her for week long hikes, with a sitter she's familiar with, but when I return it seem to take her a couple days to become familiar with me again. A child can intellectually understand taht daddy's out in the woods but a pet truly doesn't know what's going on and probably thinks you've abandoned her.
