If you are attacked by a dog, it's likely that the owner will be held responsible. New Jersey is a strict liability state, which means it's the owner's responsibility to keep his or her dogs under control.
After a bite, you may have many medical concerns including worrying about tetanus or rabies. Both can be transmitted by dogs without proper vaccines. When you are bit, going to the doctor or hospital is not only wise but imperative to prevent infection. You may need a series of rabies shots or a tetanus shot to prevent serious infections that may be fatal if left untreated.
