Sorry this has happened to you. Most of the dog runners I know are pretty courteous but invading another hunters space has happened. Personally i would make the law require dogs authorized only on lands greater then a certain amount of acres. 10 acres isn't big at all and only takes what a minute for a dog to get something moving and off the property? Dogs don't stop and keep going. Other then one group think all I know run on land 150 acres or more.
