I have no doubt that the pits destroyed 400lb. feral hogs. They were bred for “Bull-baiting” (killing bulls for entertainment) before having terrier stock added for pit-fighting use. They kill much livestock every year.
I have been told that “pit bulls are used in hunting all the time”. The Dogo Argentinos who mauled one of their owners in San Fransisco ( a large scale breeding operation in a residential neighborhood) last month are also listed as “hunting dogs”.
I believe that I have mentioned on another thread that the hunting of feral hogs is the only legitimate legal use for pit bulls that I have found, and that they are, as you say, very good at it.
I have also been told anecdotally that some hounds are about the only breed-type that can take a pit bull down.
But hounds do not have the genetic deficiencies that the pit bull breeders have selected for. And that genetic “deficiency” is an item that has been bred OUT. It has been removed. It cannot be bred back IN.
Hence the breed problem.
I've worked with a lot of hounds, and I sure haven't run across one that pound-for-pound could take a pit bull. They are quick, and their jaws are just too strong. The one I have only weighs 60 lbs, and he could easily crush the bones in your hand if he ever seriously bit you. All those "indestructible" dog toys I buy don't last a day in his yard. His favorite are those "monster" dog tires that look like 8" lawnmower tires. He can have those in pieces in no time.
I'll make sure he has a happy life, but when he's gone, I won't have another one. Pits are high-maintenance, and you always have to be careful not to p!ss them off. I've had 100 lb Doberman's that weren't as dangerous as this dog.
