This is not a problem we have in the New York suburbs, so take my suggestions for what they are worth. Feral pigs are a huge problem because swine are intelligent, adaptable, stubborn, and capable of prolific breeding. They will not abandon an area unless they are pressed very hard. Even when hunted hard, they tend to become exclusively nocturnal. A barking dog will not run them off very far, or for very long.
If you want a dog to merely harass, hector, and generally worry pigs, one of the herding breeds (Heelers, Aussie Sheps, Border collies) would be a good choice. I think you could count on one of those guys to turn a charging sow or hog.
If you determine that thinning the herd is the way to go, a Jagdterrier (or two), or a Decker Terrier (or two) would be a good option.
But like Norway Rats and Coyotes, there doesn't seem to be any way to permanently eliminate these pests. If you rid your property of swine, they will migrate back from adjoining properties. If you have neighbors who supplement their incomes with pay-to-play hog hunting, you can forget about seeing an end to it. They may keep releasing domestic swine to keep populations up.
