[Beya]

Its all normal,as long as he's not growling at you, I wouldnt incourage the behavor cause I think it could turn to a habit you wont want. I have 3 boys and they always want to play tug a war with my Beya and then my boys cry when beya bits there hand while playing to rough. I know my Beya gets caught up in the action when she is playing and starts shakes her head and running everywhere, its a way of them letting out there own stored up excitment, But your pup is young enough to let him play and train him at the same time.
