"causes a person to believe that it will attack and cause bodily injury."
Great. That's 3/4 of the urban population when they see any dog.
.......the rest of the quote......Under the state's Health and Safety Code, a dog is considered dangerous when it causes bodily injury to a person in an unprovoked attack and causes a person to believe that it will attack and cause bodily injury.
I'd say this man had legitimate reason to believe that the dog intended to cause him bodily harm.
Very true; The other day, a FedEx guy flipped out because my toy poodle walked by the open door. Didn't even look at him, but he started yelling at me to "get the dog, I hate dogs!"
