Common Sense Note
Parents need to know that the star of this reality show is a former convict who now spends his time hunting down fugitives from the law. This means that his work takes him to some seedy spots (including drug-infested neighborhoods) and gives viewers a good look at some hardened, careless criminals. He sometimes threatens to use force, but actual conflicts are rare, and violence isn't a big issue.
Chapman sometimes threatens to use force on suspects, and he'll hold down a suspect while he handcuffs him.
Fairly mild: "Goddamn," etc.
Enforces the importance of following laws, since the consequences of breaking them won't be pretty. The Chapmans have strong family relationships. Dog is a colorful character who says what he thinks and isn't always PC. The behavior exhibited by suspects is hardly role-model worthy.
Drugs / Tobacco /
Some of the areas Dog visits are clearly drug-infested -- and many of the people he apprehends are users -- but no use is shown.
