what is it you are wanting in a "catch dog"

I like your post. As you know to get one of these dogs your talking about takes yrs and many dogs to get one like that. many dogs will get close but few will have all you are asking. I have had many and been around bulldogs my whole life have had many different lines and styles for me the 40 to 60 lb pit is the best for me. the ones with temperament and heart will make the cut for me and teach all my dogs to set come with leash training way before they hunt if they don't sit they don't eat. Food control works best for me to achieve these goals back to what you said most people won't take the time to do all those things your talking bout but if you can you would be happy
