Going pretty good and silent on track...obviously the guy lied because the dog sure didn't start barking on track because he got a new owner
it's a good chance the dog ain't even started, and has probably only seen a hog through a fence but that's speculation.
I don't see much working, because the dog is barking for a reason. It's instinct for him and he thinks he's doing right. It's hard to change instinct. I'd be inclined to say trying to change him would do more harm then good. But if you're not worried or care about ruining a dog, try it all, you might just get lucky.
