They may be small, round, and sweet, but the mugs on these pugs can't always be believed.

Hidden beneath the big eyes and innocent-looking faces often lurks a pug who has waddled to the wrong side of the tracks.

Petty theft, bribery, fraud, vandalism, even lewd and lascivious behavior are well documented in the mug shots of these pugs caught in the act of their pernicious crimes.

Humorous? Yes. Funny? Not if you believe that pugs should be a little more decorous than this unruly bunch.
