In many jurisdictions, this won't help you and may actually increase your change of being held liable. For example:
>...A Beware of Dog sign may or may not count as protection against lawsuits. In Alabama, the court is likely to consider that if you need a sign telling people to beware of your dog, then you already know that the animal is dangerous. This can still apply even if your dog has a lack of violent history.
