This ordnance listed in the article is interesting, don't know how it would apply to hunting dogs running on posted property.

"According to authorities, the county has a specific ordinance prohibiting dog owners from letting their dogs run free. It simply states: "it shall be unlawful for any owner or custodian of a dog to permit the same to run at large at anytime within this county."
Under the ordinance, a dog can be found to be running at large if it is roaming, running or self-hunting off the property of its owner or custodian and not under its owner or custodian's immediate control.
The penalty for owners who are found guilty of the offense for the first time is a fine of up to $100. Each second and subsequent conviction is punishable by a fine of up to $250 or imprisonment for up to five days, or both."
