All I have to say about any of this, is that ya'll have some well trained dogs if you can stand at a fence and call them off when they're looking at a hog.
If they are looking at a hog that is when I will go get the dogs. The barking may get a land owner to shoot them thinking they are barking at his animals. Plus if they are on the pig they could get hurt. I can call dogs off a track but looking at a pig is different. Just know if you jump that fence you are wrong. That is why I drop any knife and mule tape. Because I know I am wrong but I am choosing what I feel is less wrong. But if a land owner or the law shows up I will show respect and admit I am wrong. I don't have GPS but I start calling them when they get too close to a fence. I have been lucky and never had a problem by the grace of God.
