I guess you didn't watch the Mastermind series (all true stories) where the burglar would mainly only rip-off mansions that had an alarm and a dog or two on duty.
He figured if they didn't have at least that much, there wouldn't be much in the house worth stealing. And he never harmed the dog, just knew how to quickly train them. And even did it when the owners were home (but they had no clue while it was happening).
The guy finally got caught after many years when he had already stole millions, but he became addicted to his crimes and couldn't stop and then finally got busted.
