The Pitbull being the premier fighting canine, wild or domesticated, you betcha, assuming he's not caught napping like the Boxer appears to have been.
PS And, likewise, a wolf would be equally unwise to challenge a Greyhound to a race or a Bloodhound to a trailing match. Nor, however, should any of those dogs challenge a wolf to a survival in the wild contest.
No taking your money in a fools bet. Bring your pit bull(s) and I will put you in a place where they will have contact with a wolf(wolves) inside 48 hours. If any pit bull(s) survives the encounter, I will pay the expenses for the trip.
All you have to do is show up and walk them up and down a road couple times in daylight and then stay out in the are with them at night.
