personally I will be selecting for dogs that are rougher than most, where I live is hilly and scrubby and sometimes they take some stoppin'. Dogs that run behind barking are culls in my book. Eventually I would like dogs that can be "sooled in" to catch at the bay. So to answer your question. I'll be breeding for hunting ability and stopping ability. I should add that dogs that won't rig (we say "utefind") are also regarded as culls
I know y'all run different. But any dog that just barks will not stop many hogs. But a catchy cur dog does not retire. Just a thought. You have obviously thought long and hard plus you are way smarter than me. But I want my curs to put a tooth to stop a hog and then sit back and bay. I expect them to stay bayed until I get there. Sometimes things are crazy and I don't want to worry. Just food for thought not criticizing. Plus I respect that people want to run different and that is good too.
