“Well, my mother told me about a dog her father used to own when she was a little girl,” said Bunny, as he and the boys walked along with Mr. Boardman, who was going to mend the fence so the cows couldn’t get out again. “And this dog my grandfather had would chase pigs out of a field when he saw them, even if he was a long way off. So I thought maybe if that dog would chase pigs, my dog would chase cows--and he did.”
