Fadey's right, he is trying to climb up the household heirarchy (pack) and see's you as an easy touch, NOW is the time to put him back in his place, be bold and firm but fair.
Does your other half dote on him? That must stop, I did dote on my Border Collie and we've had problems with her getting above her station cos she's "Daddy's Girl" Trying to put that right now!
Dogs need to be led or they will take over!
