Barkley is a great circus dog. He can walk on his front legs, and he can walk on his back legs.But Barkley is getting to be a great old circus dog. He can't keep up with the younger dogs, and he has problems when he joins the other acts. Soon he thinks he will have to leave the circus and the children he loves.Funny and sad, Barkley joins Syd Hoff 's inimitable cast of characters. Children who love dogs and circuses will love Barkley.
