IN TEXAS,YOU ARE CONSIDERED TO BE TRESPASSING IF YOU ENTER UPON LAND THAT KNOWINGLY THAT IT'S NOT YOURS AND YOU DO NOT HAVE PERMISSION,NO MATTER IF YOUR DOGS ARE THERE OR WHATEVER.I KNOW THIS,BECAUSE I RECEIVED A TICKET FOR THAT VERY REASON.AND IT WAS EXPLAINED TO ME BY THE GAME WARDEN AS HE WAS WRITING.HE SAID THAT IGNORANCE WAS NO EXCUSE FOR THE LAW.IT WAS AN EXPENSIVE LESSON.
The knowingly part is wrong. It does not matter if you know or not to be trespassing. But to get a ticket it may. I know I was stopped once but there was no fence for me to know. But you are also trespassing when your dog trespasses. But your dog does not know what a fence is. If there are damages when you are trespassing you are liable for them. That means if you go to court you will have to pay. Save the money and do the right thing. But I always train my dogs to stop on command. It can save their life with cars.Take a rope and tie an inner tube to a tree (some people do not use the inner tube). Then tie a long rope to the inner tube and the other end on the dogs collar. With retrievers we throw something but make the dog run. When there are just a couple loops of rope left yell stop. They will not stop the first time and they will hit the end of the rope. Repeat it changing the length of the rope. Your dog will learn very fast to stop when you yell "stop." Some dogs I have trained like that will stop and come back, but they all stop. It is great when working a group of dogs and you yell stop and they all stop dead in their tracks. That way you can stay on your side of the fence and have a command that you know will work.
