I would think that it isn't good for them to get all riled up when you come home. Mine do the same thing though, and I felt just the way you do. It has been said to me that it's an issue of respect of your space and your place as the leader as well as a security issue. Your pup is secure with you. Having had plenty of opportunity to watch mine react when someone comes home, they jump and go nuts on everyone but me. They also all but disregard everyone else's commands too. Trust me, your pup loves you!
