Dog bite laws in Louisiana apply to injuries the owner of the dog could have prevented, says Nolo. In Iowa, the person bitten by a dog must prove he was not committing an unlawful act that may have contributed to the bite.
Dog bite laws vary widely from state to state. In Hawaii, an injured person must prove that the owner was negligent, unless the dog was known to be vicious, states Nolo. Tennessee dog bites law do not outline exact liability, but the dog owner can be held liable whether or not he knew of the dog's ability to be dangerous.
In Arizona, the laws states that the owner of a dog that bites someone is liable when the victim was lawfully in or on private property, including the property of the dog's owner, or was in a public place. The law further states the liability of the dog's owner stands regardless of whether or not the owner had knowledge of the dog's viciousness, explains Nolo. In order for the person bitten to prove liability, he must show that his injuries were caused by the dog in question, that he was lawfully on private property or in a public place when he was bitten, and that the defendant is the owner of the dog.
