That's true, Mygala. One way you can get some advice is to call whoever does your home insurance and ask how they cover dogs. If it is an apartment, the property will have insurance for residents that would cover your animals. Ask the apartment manager. I got the information where I am and they said the sign warns the person entering the property, it can also cut down on burglaries, and so while it may not stop a lawsuit, it goes a long way in showing proof of responsibility, especially if the bite happens inside the yard/house and the dog is not running loose.
A dog with a history of biting is considered aggressive and yes, that would count against the owner, but a sign in general is a good warning that there is an animal, whether it has ever bitten or not.
One of my neighbors is a cop, and I brought this up with him, and he said if someone complains about a dog biting them, the sign can make a difference in charges being filed in some cases against the owner, too. If a police report is filed for the purpose of a lawsuit, the finding of the police is very important.
Pets are always your friend no matter what.
