Gameness has a lot to do with health and condition of the animal hunting,and what they are hunting .a good game animal in the hands of an idiot won't be so game ,to sum it up some people can screw up anything they touch.
Now back on the RBJ ,our line is a little different than most.we have focused on keeping it. 50/ 50 and only breeding solid bulldogs ,total package hunters .smart ,wide open barnstormer's,deep game ,and that heavy mouth .while some only focused on gameness or mouth ,and end up bouncing here and there ,we bred the ones that had it all .the end results total package dogs with a high percentage in each litter .this practice is what we call select breeding .i can't take anything away from any bloodline just certain strains of the bloodline ,you need to know what breeder has the best line .
