A good dog is a good dog open or not I have ran both ways with good out comes ether you like them or ya don't. Know the wrong open dog can cauz problems but for the most part I see no difference other than the open dog may go further to stop it but I think in most cases it just becuz the open dog opened way back giving the pig a alert that something is coming for him the rest is on the quality of the dog
there good ones both ways I like hunting silent dogs but man there is something about a real good open dog that I just love nothing like hearing a loud hound or cur
