Arizona dog bite laws force dog owners to be strictly liable if their dog attacks a human being. Arizona, unlike other states, enforce strict liability laws which make the dog owner liable for damages even if the dog has never shown vicious tendencies before the attack. Other states allow one bite before the dog owner becomes liable for their dog’s actions.
Just because a person was bitten, doesn’t necessarily mean that the dog owner is responsible. There are a few defenses to a dog bite claim that exist. For example, if the person that was bitten was trespassing, the owner of the dog and property may escape liability. If the person that is bit provokes the dog before the bite, the owner may not be liable.
