If you are unfortunately bit by a dog, you can ask the dog’s owner if their dog has ever bit someone before? They may answer you, they may not, depends on what they know about the law, because you have to prove that the dog has vicious propensity.
In addition to wanting to be able to recover money for your injury, what people want to know is if the dog has received its rabies shots? If you’re bitten and its bad, you go to a hospital or a doctor, they’ll need to know the answer to that question to know how to treat you.
If they can’t determine that the dog has been vaccinated for rabies, you may then have to undergo the treatment for rabies to make sure that you’re protected. That treatment is not pleasant, so if it’s any way possible to learn about the current status of the dog and its shots, you should do that because it will help you prevent the rabies treatment that you would need.
