some faulty are : 

IN F1 BF-JRT >>>

1: TAIL:  THE MAJOR CONCERN .THEY BORN WITH NORMAL TAIL, BUT WITH THE TENDECY TO COME UP LIKE TERRIER. JUST ONE FEMALE HAVE CORRECT TAIL FOR BULLY STANDARD. SO I DECIDE TO DOCK ALL.

2: BITE: 3 SCISSORS (CORRECT) AND ONE MALE FAWN  UNDERSHOT SLIGHT

THE NEXT GENERATION WITH APBT WILL BE ABLE TO FIX THOSE FAULTY

IN REDCAPO'S MARECHAL BULLY XL : FAULTY : TOPLINE SLIGHT HIGH REAR (ACCEPTABLE FOR XL) AND UNDERSHOT BITE 

THE NEXT GENERATION WITH APBT WILL BE ABLE TO FIX THOSE FAULTY
