 The Master and Mistress buy a female collie puppy named Lady to be Lad's companion and mate. Lad becomes her protector and slave, as she bullies him from his food and the best places to lie, and endures the flashes of nasty temper that lead her to bite his ears and paws. As she grows older, she becomes a generally well-behaved house dog, but when she is eight months old, she tries to attack a beloved mounted bald eagle belonging to the Master. He whips her and then locks her in a shed for the night as punishment; however, during the night it catches on fire. Lad desperately tries to break down the door to free her, then howls in agony, before jumping through its high window to join Lady inside. The Master, awakened by Lad's howl, arrives in time to free them both, though both have badly burned coats.
