Well it's good that you're wanting to start hog doggin'.....we need all the help and recruitement we can get. You've already gotten some good advice I see. I commend you for at least asking for advice as opposed to assuming that since you've been a few times that you now know all there is to know about it....
One thing I might add to this advice is to be dang sure that you are capable of properly caring for your dogs when you get them. It's not ok to just tie a chain around a tree and throw out a barrel with no front on it if you live where it gets cold in winter. If you choose to have dogs of your own.....you are duty bound to take proper care of them....otherwise....just don't get any. Take care of your dogs......failure is not an option here. Good luck and keep us posted about your venture.
