All those dogs average 100 to 200 lbs the CC being the smallest I believe. You are probably looking at 140lb mininum. Male Boerboels can get to 195+ if large, Bullmastiff 140ish, CC about 110/120, DDB 150ish PC about 135ish. The weights I posted are average male weights. Oddly the BB is the biggest. This is going to be one interesting dog. Can you share some pictures with us?
