blue pit bulls

Blue dogs are just "NON-GAME-BRED" dogs with blue color, period. they may be good at catching hogs, I don't know, but they are NOT TRUE American Pit Bull Terriers. They are too big, too bulky, heads too big, lack stamina and endurance and HEART. Now, with that being said, they may make great catch dogs on hogs, and I think that was the original question. When I say they lack heart, I mean compared to the elite of the breed. They may have all the heart they need to catch a hog, and that's good enough, but they are not gamedogs, never were, never will be. Also, there is no such thing as "lock" or "lockjaw". A bulldog's working parts that make up his jaw structure are no different than any other dog, a good one just won't let go because he chooses not to let go, has nothing to do with lockjaw. Also, this "locking" is an urban legend. The best fighting dogs will gladly let go of one hold to get a better one.
