A prior bite is only one way of showing vicious propensities. In fact, the courts of New York have previously held that if a victim can prove that the dog has a dangerous nature and the owner knew or should have known of the dog’s dangerous behavior, then the one bite rule will not apply. Some examples of a dangerous nature could be that the dog had previously been known to growl, snap or bare its teeth or the dog had a tendency to snap at people. The owner may have let it be known that the dog is an “attack dog” or warns people that “the dog bites”.
