I love this behavior: My yorkies face off in opposite ends of my office; staring each other down. They are sitting like sphinxes just waiting for one or the other to make a move, then, usually the 9 month old will attack his older sister and start play fighting. You never know just when he is going to strike, it could take a few minutes! It's funny waiting for the onslaught
Is this a common behavior? I have watched a lot of yorkie videos in my time and not seen this (gotta get a video camera).
