If any of us knew a way to fix that problem we wouldnt have to work any more.
Hogs really arent all that fast compared to dogs but they are good at using the terrain to their advantage. They can bust through thick vines and briars easily and take a break while the dogs are fighting and picking their way through it. When they get close porky will just run a little further. If he can get far enough ahead and doesnt do anything foolish like go out in the open he can stay ahead.
You can try catchy dogs or just one or two loose baying dogs or keep doing what you are doing. Sometimes you win and sometimes you loose no matter what you do.
