Nothing to do with bulldogs but bred English bulldog to female boxer then took dogs that look more like English bulldogs and bred back to stud and in three generations got a little longer legged more athletic looking no skin or eye problems natural birth English bulldogs, sold them at flea markets off the back of the tail gate of my truck as the poor man English bulldogs sold as many as I could produce from repeat customers they were smart and loyal it lasted till my little stud died. Yours in the Game Johnny
