pulling his body by the front feet,
the hind legs dragging flat.
Without thinking,
you called the Humane Society.
They came with a net and went for him.
They were matter of fact, uniformed;
there were two of them,
their truck ominous, with a cage.
He was hiding in the weeds. It was then
you saw his eyes. He understood.
He was trembling.
After they took him, you began to suffer regret.
Years later, you remember his misfit body
scrambling to reach the others.
Even at this moment, your heart
is going too fast; your hands sweat.
Here Stone makes a direct change in time by saying “years later”. The years later help us understande that this moment with the  injured pig is still remembered. 
 Misfit meaning something that does not fit properly.
