*lay down on ur belly on the floor. call ur dog(s) to u. if the dog(s) lays down and trys to get their head under yours (they might lick u in the process,) then they know ur the alpha. BUT if ur dog just stands straight up looking down on u, then u might have to work harder on who's boss around the house.
I guess I have to work harder then, although my dogs mind my instructions, but quite frankly they looked at me like, "what the he.. are you doing down there on the floor?"
