"Go get mama" or "Go get daddy." It is soooo cute. Whoever you tell him to get, he'll go and lick them in the face over and over...so then I tell him to go get daddy so I can breath and it goes back and forth!
He is so smart...there are probobly a list of 20 or 30 things that we can tell him to get and he will go and get the right thing. That's probobly true for all dogs, but I'm just a proud mama.
