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.
Well, if you gave up after one trip....I think you gave up to soon. JMO
