A Trick

This trick was tough for Riff to learn - possibly because of the length of his back, and the narrowness of his hips.  I used my arm or hand to steady him at first, but he always sort of melted sideways without help, although he seemed willing to try.  We attempted the trick once every week or two, for less than a minute each session.  I had made up my mind to try it Just Once More, when he suddenly decided to splay his back feet out to the side to keep his balance.  And he seems to use his tail for a "tripod effect."  I guess he needed extra time to figure it out on his own.  Or perhaps he needed to grow into it?  Now he sits-up willingly, and easily.  Such a cute boy!
