CYJ, I also understand exactly what you are saying with the zilla dog as well.And Im not breeding him because of the bullet blood in his pedigree,cause he have other blood as well. I breed this dog because of what he throws and his ROM father threw. I truly believe that some bulldogs will be put on the ground off this dog in the near future.You have to see the animals he put on the ground to truly understand and to know the dog. I figure it wouldnt hurt to research the dog behind him,to find where certain traits come from. In hopes that maybe you can keep these traits going on through many generation. thanks again
