I am wonderfully happy with our big dogs' behavior with Hachi. They seem to trade off as to who babysits him. Shyla had Saturday off from playing with Hachi, and R did yeoman's work.
Actually R seemed to like it.
R has a very different play style than Shyla does. Shyla likes to play with toys while R likes to wrestle.
And he likes to bare his teeth!
I just love Hachi's facial expressions before he "strikes" R.
During wrestling breaks, Hachi played in his tunnel. He adores it! He does laps around the living room that include sprints through the tunnel.
