I own my own land and spent alot of money to do so. Trespassing is trespassing wheather by a dog, human or a farmers cattle. The bottom line is the owner of the dog, cattle etc. is responsible for their control, and my state is specific on landowners rights when it comes to animal trespass but my property is just that: MY PROPERTY! My eye sight is not what it used to be, tresspassers whether human or dog, you better be running!
