NY follows the 'one-bite' rule — but it's easier to prove than it sounds.
Petrone v. Fernandez (2008) confirmed NY's vicious-propensity rule: strict liability only attaches if the owner knew or should have known the dog had vicious propensities. But 'vicious propensities' include growling, lunging at strangers, prior nips (even without breaking skin), being kept as a 'guard dog,' or being trained to attack — not just prior bites. We dig for this evidence.
