This has been stated, but I'll mention it again in a slightly different way.
Dogs have different personalities, and different intelligence levels.
I have an Australian cattle dog. Well, actually, my wife does. They're one-person dogs.
My wife's "minimal research" did not fully inform her of the breed's characteristics.
Cattle dogs are right a$$holes. They're pr|cks. They are bred to drive thousands of head of cattle thousands of miles through inhospitable terrain, by biting them.
Because of this, they are also impervious to weather, and to injury.
They are also very smart, in a sneaky sort of way, and insanely persistent.
And our SOB is 85 pounds of solid muscle, even though the breed is supposed to be 20 to 40 pounds.
We tried a shock collar on our idiot. Several, actually.
First, on the maximum setting, they had absolutely no effect on him. Once he had fixated on chasing a horse (time to acquire target approximately 1/4 second), you could hit that thing over and over. If it was on High, he would flinch a little, but wouldn't slow down at all.
Plus, he figured out right away what the collar was. So he'd just walk off into the woods and come back without it. Lost about three of them, never found any.
He says inside the fence now, and tries to chew through the wire as he barks at passers-by.
Point being, whether a radio fence and a shock collar will work for you is entirely dependent on your dog, plus, if the dog is all charged up to chase something on the way out, he'll run right through it, but it might keep him from coming home the other way when he's calmed down.
