I've always felt if in public keep your dog on a leash no matter how well trained it is.
1. Typically the law and why be that person.
2. Sets an example of responsibility. Sadly we all know this is useless.
On our propery our Ridgeback is always off leash, but the little guy he stays on a retractible, being a wild dog for most of his life if he sees something, he's after it. so this gives him some level of freedom to roam but gives us peace of mind he won't end up coyote chow if he left and got lost.
You have to keep the neighbouring farmers in mind too!! A lot of them will not tolerate a strange dog on their property if they have animals.
