My dog

Have you tried hiding from a dog, behind a tree? You can't look out (I've tried that and the dog spots you straight away), so you have to stay there and listen. You might consider edging around the tree, to keep hidden. My dog will make a dash for the tree and catch me out, usually darting from the opposite direction in which I'm looking. She's also started hiding behind trees and watching me while I throw her a stick, then she races out and pounces on the stick, maybe wishing it were a rabbit.
