I never see them. I think people around here think that if you have a sign and your dog bites someone, you will be more liable because you knew your dog was dangerous.
If I did see a sign, I would probably think people are wanting me to believe there is a vicious dog around so that I won't go on the property, etc. It would probably make me believe there wasn't, but whatever. It is against the law in Ohio to debark a dangerous dog. So, if I were to see a sign and not hear a dog, I would probably figure the dog was out.
There is absolutely nothing I would do differently if there was a beware of dog sign. I don't open people's gates and tramp over their property, so that doesn't really matter. If there is a reason I need to go up on someone's porch, I will go, sign or no. Posting a sign does not mean you can let the dog run around loose, you still have to contain them to your property, and have safe access to your front door, so it just wouldn't make any difference to me.
But again, I never see them.
