I don't have dogs, but a friend has a rather energetic lab. One thing that I know she did was before they brought bubs home, they brought home the blanket that he was wrapped in when he was first born. It was obviously a bit gross, but totally covered in his scent. This allowed their dog to get used to his scent before he got home. I can ask what else they did if you like. 3 months down the track they quite happily leave bubs on his mat or in his bouncer in the lounge room while they are in the kitchen getting lunch or doing dishes, etc and they have no issues with their dog roaming the house. He walks past and checks on bubs, but mostly seems to leave him alone.
