Zuchttauglichkeitsprufung (called the ZTP or BST) translates as "breeding suitability test," and certifies that a Rottweiler is acceptable as breeding stock. In Germany, a Rottweiler must
attain this degree before being bred.

The dog to be tested must be at least 18 months of age and be tattooed. The dog must not have any disqualifying faults according to the January 16, 1996, FCI standard. The dog must have successfully completed a  BH or a VDH sanctioned BH. The ZTP is provisionally awarded until the dog attains OFA certification or has ADRK HD hip approval.

• There are several phases in the ZTP. First, the dog is measured and weighed. A conformation critique is given, which includes the dog's eye color and any abnormalities in dentition.
• The dog then performs a light obedience pattern during which a gun is fired twice, to test the dog's sureness in the face of noise.
• The dog must heel through a crowd and allow several people to close in on him without a display of fear or unwarranted aggression.
• The dog is then rated on the characteristics of self sufficiency, temperament, tractability, courage, protection drive, excitability, fearlessness, attentiveness, mistrust, fighting drive, and hardness.

All of these, plus the reaction to the gunshots, are noted on the dog's ZTP form, along with his measurements and critique, which is kept on record by the sanctioning club

In addition to the gun sureness test and the crowd test, a courage test is also
performed. In the courage test, the Rottweiler must bite the padded sleeve on the
agitator's arm, take threats of two hits over the withers with a padded stick, be driven in the
fight, and release the sleeve upon command at least once during the exercises.
Then the Rottweiler must guard the agitator until the judge signals
the handler to pick up his dog.

BST- ZTP

With the dog on leash, the handler reports to the judge. The dog's tattoo or microchip number will be rechecked by the judge before the protection work begins. On instruction from the judge the dog and handler approach the blind on leash. At a distance of approximately 30 feet away from the blind the handler will remove the dog's leash and continue approaching the blind while holding the dog by the collar. At approximately 12 feet from the blind (a line may be marked on the ground) the judge will instruct the helper to come out of the blind and attack the handler. The handler must immediately release the dog and remain at the spot of releasing the dog until told otherwise by the judge. The helper will come out immediately from the blind when directed by the judge and attack towards the handler. The helper will catch the dog on the sleeve, drive the dog and apply two stick hits with an interval of 2 or 3 steps between hits. The helper will continue to drive the dog briefly, approximately 3 to 5 paces, until directed by the judge to stop. The dog should immediately go to the helper and grip the sleeve and continue gripping the sleeve while being driven. When the helper stops, the dog outs, with or without command from the handler. The dog must guard the helper intently. On instruction from the judge the handler will go to the dog and put the dog on the leash. The handler, with the dog on leash, will heel down the field to a blind designated by the judge. On instruction from the judge the handler will leave the blind (on leash) and heel to the center of the field. With the dog in the basic position, the handler will remove the leash and hold the dog by the collar. The dog must remain quietly by the handler’s side. On instruction of the judge, the helper will come from behind a blind that is designated by the judge (approximately 40 meters away from the dog and handler) and walk at a normal pace to the center of the field. The handler may challenge the helper as he leaves the blind. At the center of the field the helper will turn and runs towards the dog and handler in a threatening manner. The handler will release the dog and remain at the spot of releasing the dog until told otherwise by the judge. The helper will catch the dog on the sleeve and drive the dog 4 or 5 paces (no stick hits). The dog must grip and remain on the sleeve while being driven. The helper stops and the dog outs, with or without a command from the handler. The dog must guard the helper intently. When instructed by the judge, the handler will go to the dog, put the dog on leash, heel back to the judge and report that the routine is completed.

Advanced Breed Suitability Test

With the dog on leash, the handler reports to the judge. The dog's tattoo or microchip number will be rechecked by the judge before the protection work begins. The dog and handler assume the starting point designated by the judge for the blind search and removes the leash. On instruction from the judge the handler sends the dog to search the blind while remaining at the center of the field. The handler must show two blind searches, one to the right and one to the left (or visa versa). Failure to search the empty blind is grounds for dismissal by the judge. If the dog does not find the helper in the blind, the handler may resend him. After being sent unsuccessfully three times to the helper the routine is terminated. When the dog reaches the helper he must bark without gripping. The dog must hold the helper attentively and closely, with intensity and self-confidence, barking energetically and continuously until he is called out. The handler must remain stationary until instructed to approach by the judge. On instruction from the judge the handler orders the helper to step out of the blind. The helper moves at a normal pace to the designated location for the escape. On signal from the judge, the handler moves with this free-heeling dog to the designated spot for the down prior to the escape. The distance between the dog and helper is 5 paces. On instruction from the judge the handler leaves his dog in the down position and moves directly into the blind, maintaining visual contact with the dog, the judge and the helper. On instruction from the judge the helper tries to escape. The dog must immediately prevent the escape effectively and without hesitation, by means of a energetic and strong grip on the sleeve. On instruction from the judge the helper stands still and the dog outs, with or without a command from the handler. The dog must guard the helper intently. On instruction from the judge the helper attacks the dog and gives two stick hits. The dog must immediately counter the attack forcefully by gripping the arm. On instruction from the judge the helper stands still and the dog outs, with or without a command from the handler. The dog must guard the helper intently. On instruction from the judge the handler will go to the dog and put the dog on the leash. The handler, with the dog on leash, will heel down the field to a location in the center of the field designated by the judge. With the dog in the basic position, the handler will remove the leash and may the dog by the collar. The dog must remain quietly by the handler’s side. On instruction from the judge, the helper will come from behind a blind that is designated by the judge (approximately 40 meters away from the dog and handler) and run to the center of the field. At the center of the field the helper will turn and runs towards the dog and handler in a threatening manner. The handler may order the helper to stop and stand still. On instruction from the judge the handler will release the dog and remain at the spot of releasing the dog until told otherwise by the judge. The helper will catch the dog on the sleeve and drive the dog 4 or 5 paces (no stick hits). The dog must grip and remain on the sleeve while being driven. The helper stops and the dog outs, with or without a command from the handler. On instruction from the judge the helper attacks the dog and gives two stick hits. The dog must immediately counter the attack forcefully by gripping the arm. On instruction from the judge the helper stands still and the dog outs, with or without a command from the handler. The dog must guard the helper intently. On instruction from the judge, the handler goes directly to the dog and commands the dog to bring him into the basic position. The handler tells the helper to step back, commands the dog to "down" and takes the stick from the helper. The dog and handler perform a side-transport of the helper to the judge. The dog must walk on the helper's right side so that the dog is positioned between the handler and the helper. The dog must watch the helper attentively during the side-transport, however the dog may not bother, jump on or grip the helper. The group stops in front of the judge, the handler presents the stick to the judge and reports that the routine is completed.
