Lance and Tucker were playing today and did well together.  At one point during a different play session, Tucker grabbed a hold of Lances scruff, on the side of his neck, and would not let go..and I mean not let go, it looked as if Lance was pinned down and didnt seem comfortable, so I made Tucker stop.  Afterwards, Tucker and Lance were standing by each other and I was near them and Tucker starts barking non stop in Lances ear!!!  Lance just stood there not knowing what he should do, and then after all the barking, Tucker went for his ear, as to say, lets play?  

The barking in another dogs ear, what would that mean?  Is it rude behavior, or just trying to get him to play? 

The other question I have is about when Lance is rolling on his back, back and forth and then Tucker gets a surge of energy and goes bolting towards Lance wanting to play, would that be considered rude or normal play?  Tucker is usually in another room when he hears Lance rolling and comes running at him.
