Yard Signs for the Meter Reader

I sought legal advice after the Meter Reader told the neighbors that my dog bit her. She never filed a report, but I wanted all bases covered. IMO this whole thing is rubbish, but the lawyer says I need to take simple measures to help prevent future interaction between the dog and the Meter Reader. I bought these. One is for the deck, and the other will be mounted by a large gate on the other side of my  yard. (The blue sign hasn't arrived yet.)  I also ordered a custom sign with phone numbers and the words 'Please contact owner before entry' at my lawyer's advice.  My neighbor has agreed to put my baby inside or on a leash if I'm not at home when the Meter Reader wants in the backyard.  *rolling my eyes*   The only thing intimidating about him is his size, but whatever...
