I guess they're out there but I never had a bulldog that wouldn't catch.
I had a 2 year old pit that was my catch dog. I came home from work one day & he was dead on his chain. A couple friends & myself started lookin for another pit to replace him. My friend found a lil black & white male & picked him up for me. I took him to the bay pen & he wanted nothin at all to do with the hog. I tried to push him in the direction of the hog & he started squealin & whinin & doin his best to get as far away as fast as he could. So yeah, they're definitely out there.
