Unfortunately, legally, unless your property is completely fenced and gated with a lock on it and/or well posted with no trespassing signs, anyone can legally come to your door, unless you have a previous restraining or no contact order against them.We have our dogs behind an invisible fence, and someone stopped to “leave a flyer” on our door when we weren’t home. They filed a complaint because our dogs ran out barking and scared the crap out of them. We were in no trouble once my DH proved both were licensed & had rabies shots. Then he asked who it was and said he wanted to file a counter complaint for trespassing since they had no business being there when we weren’t home,
Also, if your dogs had bitten said person you would be held liable.
