Dog play is fascinating and hysterical!
Lucy spaniel invented this game today and played it over and over and over.
She takes the ball, and goes under the a-frame. Pushes the ball in the space under the a-frame, then uses her paws to pull it back. If it goes too far out of range, she barks. Zora grabs it, decides it is too slimy and gross, and spits it out. Lucy takes the ball back, and under the a-frame to play her game once again.
