My thoughts are if you are in really thick country, getting outrun is just part of it. Chances are your dogs are not getting anywhere close enough to the hog to put teeth on it. I am in no way saying your dogs are slow or suck

we hunt thick east texas stuff almost every weekend. The best way i have found to stop the running sob's is to run the air out of them. We ran a 60 lb sow saturday for 3 hours then i kicked my chrissy dog to the race and within ten minutes we had a cought hog. Get them runnin suckers tired and kick a fast dog to em to get the hog to give up. Cold pack that ass

or get some straight up rough yellers that i keep hearing about that will shut down a runner. Lol.... i have invited some of those guys with me in the past and they haven't made a believer out of me yet. Good luck
