I know some people who have successfully titled dogs in PSA (protection sports of america) which is one of the harder titles to get. My friends do it the it the opposite way. Nothing but drive building, confidence building, environmental training and bite grip work on the pup until it's around a year old. At this point you have what's called a "green dog". THEN they start putting obedience into the equation, off the field. Then they introduce the obedience on the field and use the bite as the reward. The dog wants the bite so bad it will do anything for the handler. The dog is so focused on the handler, waiting for it's reward, that the obedience is off the hook amazing, under incredible distraction.
Here's a link to PSA, if anyone is interested in seeing how it's set up for the various titles. There are a lot of cool pictures too, and yes, there are some bully breeds competing. Also look at the obedience requirements- level 1 isn't so bad, but look at level 3- you need a badass dog to pass this level:
PSA Level 3
This level of the PSA test requires the handler and dog to perform obedience and protection exercises and routines of a surprise nature. This is the highest level of achievement in PSA and is meant to be a test of the utmost difficulty and reward the most versatile dogs and trainers. None of the exercises will be announced before the trial. The goal of the scenarios shall be to challenge the handling skills of the handler, and to challenge the training and nerves of the dog.
Dogs who figure out a way to solve the problem shall be rewarded rather than penalized for not conforming to the outcome envisioned by the judge in making up the scenario. Handlers should be afforded the ability to make sensible decisions about the use of their dog, and judges will encourage creative realistic thinking on the part of the dog and handler. For example: Snow fence is used to simulate a wall (impenetrable barrier), but the dog realizes he can crawl under or jump over it in order to neutralize the threat or apprehend the decoy. This will be rewarded, rather than penalized.
Judges will also not set up scenarios that are “doomed to fail.†Judges must not reward weakness of nerve in favor of control. Example: We will not ask a dog to out in the middle of a severe attack while the attacker is still fighting the dog successfully. A dog that is likely to perform this successfully is one who doesn’t want to be engaged in a fight from the start, versus a strong dog who is likely to continue fighting until he has reasonably neutralized the attacker.
PSA 3 Obedience:
The obedience phase will be 100 points. At this level, dressed decoys are allowed on field to serve as distractions during obedience exercises. Agitation (within reason and accepted judging standards), passive or agitated bites are allowed during obedience. The obedience must include at least six of the 10 following mandatory exercises, but is not limited to these exercises alone:
(1) Off-leash heeling, including turns (left, right, about) and change of pace, return to heel, and figure-8.
(2) Window, hurdle, or tunnel obstacles.
(3) Sit or down in motion
(4) Food refusal
(5) Change of position (sit/down/stand)
(6) Retrieve over obstacles (tunnel, hurdles, A-frame)
(7) Sit on recall
(8) A-frame climb
(9) Go-ahead and down (voraus or send out)
( 10) Directed jumping
Judges shall design the exercises to challenge the dog and handler, but care must be taken to provide exercises that are reasonable and fair to all dogs entered.
PSA 3 Protection:
The protection phase will be 240 points (4 scenario exercises, 60 points each). The protection phase must include the following mandatory exercises; however, the judge is free to set-up the exercises in any context he/she wishes:
(1) Courage test with clatter-stick hits
(2) Call-off
Suggested Exercises:
Remote transports
Object guards
Muzzle attacks
Send to hold & bark with agitation.
Simple area searches
Multiple call-offs
Tests of nerve (heavy environmental distraction)
