When I brought my newborn son home, I behaved like he'd always been there. I didn't make a big deal out of him to the dogs, or force any introductions. I made sure the dogs still received as much one on one attention as was possible, as well as including them in things with my son as part of the group. We never had any problems

The jealousy your pup is showing would concern me a bit, though... make sure to entirely ignore him when he does things like that. That is one thing I like about always having multiple dogs... none of my dogs are ever jealous of another getting attention!
