Hoping I can still talk the wife into a garden pig this summer. @jchny2000
has several, and she has mentioned using a hot wire for them, and I know others that do. I'm more of a hog panel guy myself, because I don't have room for them to pasture, and I want to use them as tillers for my garden area.
Swine are easy. Make sure they have shade, especially if they are white hogs, they will burn without shade and mud. I would put hogs right up there with dogs in terms of trainability and personality. I've always loved having hogs around, and it has been far too long since I had my last hogs, so i'm looking forward to it.
