Get the biggest, badest, meanest pit bull and put this pos in a small room together and let them fight it out. No weapons allowed.
Yes—and if he survives unleash the presa canario.
Why stop at one pit bull? Put a pair of 'em in with him, after you beat him and stab him with acid-tipped needles. Put his miserable remains through a woodchipper and dump them into a hog pen. This walking pile of steaming feces doesn't rate the space and oxygen he's wasting.
