The Leaves Of Grasp

One day while on an appraisal, to assess a work of art;
I was warned about a little Yorkie, that got mad when you’d depart!
My client said he loved company, and would kiss you if you stayed;
But his personality would change drastically, if you tried to go away!
.
He looked so small and innocent, weighed no more than just five pounds;
He laid quietly as we did business, made not even one small sound!
I made her a nice cash offer, for the painting on the wall;
She eagerly accepted it, for her, a large windfall!
.
I counted out ten Ben Franklins, and took my purchase down;
I started walking toward the front door, to head back into my town!
I felt something grasp my ankle, just beneath my Achilles;
I had forgotten her admonishment, little dog drew blood from me!

                                   Though he be little
                           He was dangerously fierce
                                  Do not try to leave
