Trying to recreate a blast from the past with a new era twist. U-No is heavy Ch Reno via Pettus' Luke (Reno x Aggie). Sinner is down from some of the best Boyles, Newman's Ch Buck (littermate) to Pettus' Luke, Gr Ch Machobuck, & Ch Tonka/Tombstone blood around today. U-No is a virtual destroyer. He as all the tools to get the job done and to finish it as well. This breeding should produce exceptionally gifted canine athletes !
