Opinions wanted - On catchdogs performance

bigA i agree to a ceratin extend. bulldogs are bred to be impervious to pain. they can feel that pain but they should have the mind set to be push through the pain and get the job done, not me slapping them to get them to act right. i've seen dogs bit so hard they have pissed right there on the spot and those dogs never made a sound they had one goal in mind. bulldogs are bred to be like that...if they don't have that mind set FOR ME i can't use them..i need a dog that doesn't need me to get them right after a big hit..they need to take that hit roll over and go get again son......and keep doing it till i say they need to stop...if they don't have that mindset they are a cull in my mind...will those dogs catch you plenty of hogs obviously they will as this dog has, but what happens when you go into another big bad sob and hits him again you are up a tree and your dogs are getting wrecked cause you took a known cull cd to the woods..its just to iffy for me..cullbuck will do as he pleases...i've got a dogo right now that if she don't do what she is supposed to do..i will take the hit to my pocket as hard as it may be, but she will get culled quick if she ain't getting the job done...
