Deep down in every dog is a wolf, -even in a Chihuahua, and there's always a pack instinct with the hierarchy of the alfa dog as as leader, in my experience with several dogs it is usually the one who feeds it, which in our case has always been my wife, with me thinking of myself as just another pack-member.
Our gorgeous Hungarian sheep dog ( the ones from which British and Australian border-collies were bred) likes to always know where we both are all the time, but it is my wife she follows around the house and garden most of the day.
