[edit] Forbes: an estimated 800,000 people each year must seek medical attention after a bite. Hospital bills can be very expensive, and an ER visit could necessitate a dog bite lawsuit in order to recover monetary compensation for damages.

My sister in law was one of them, when she was five or so. Unprovoked run-up-and-bite from an off-leash dog. Had to have a tear duct rerouted and other work on her face. Messed up their finances really bad for a couple years, like “parents not eating dinner tonight, because there’s only one can of spaghetti-o’s” bad (they were fairly poor to begin with)
