Montag observes the Mechanical Hound in its kennel, a creature of copper and steel that seems both dead and alive. It is a tool of the firemen, used to hunt and kill.

When Montag touches the Hound, it growls and reacts threateningly. Beatty dismisses it as a malfunction, but Montag senses a personal animosity. The Hound is set to his chemical combination, implying someone wants him dead.
A Symbol of Surveillance
The Hound represents the state's ability to track and eliminate dissent. Its presence in the firehouse is a constant reminder of the consequences of transgression.
