TRUE DEFINITION OF BULLDOG TO BULLDOG,HALF/BROTHER SISTER BREEDING, DOUBLE RICH PORTER BREEDING. THIS BREEDING WILL SPEAK FOR ITSELF. DOUBLE BRED ON ONE OF MY ALL TIME FAVORITE DOGS (DSP RICH PORTER). BOTH OF THESE DOGS REPRESENT HIM WELL. THEY BOTH ARE EXTREME ATHLETES AND THESE 2 TOGETHER U CAN’T ASK FOR ANYTHING BETTER. 15 YEARS OF GREAT SELECTIVE LINE BREEDING. DSP
