I need to clarify one thing first - it is rare for any dog to possess so little prey as my last patrol dog. Ususally you will find that a dog with primary fight drive also possesses adequate to pronounced prey. I also almost always start training with an adult dog (18-24 mo's). This dog is somewhat settled and generally is what is will always be. You can test with realtive certainty the dogs drives and nerves. There are so many things that can affect the eventual working ability of a puppy, that it really nothing more than a good prospect.
It is difficult to test for or even observe a significant level in a puppy - puppy testing is very subjective, as all tests are. The general behavior to look for is the pup that approaches boldly, sometimes barking, but shows no sign of fear or defense or even dominance. He is usually the number 2 or 3 ranked dog in the litter, and almost never lower. Again, it is never more than an educated guess. However, you will not be able to miss the one that has mega fight.
Remember the purpose of fight drive = the detaining or driving off of a foe. In training the pup you do just that. You will be surprised at the instinct to detain. All the initial work should be civil with loose clothing in case the puppy feels a need to punish you for moving too much. Yes, the decoy gets some bumps and scrapes, but it is well worth it in the long run. If the puppy does bite, the decoy must comply with the puppy's orders to "stand still. BTW, it is very important the handler remain quiet and let the confrontation be between the decoy and the dog. Increase the time of detainment slowly from just a few barks at first to at least 50. End the deataining session with the handler calmly walking up to the dog and pick up his leash, The decoy must keep the dog focused on him. Have the decoy walk or run away, allowing the puppy to achieve drive satisfaction through victory.
As the puppy becomes more experienced, the intensity in the detaining behavior will also increase - and the bites will become harder. Only then do you want the decoy to wear minimal protective clothing.
Developing bite in a young fight drive dog is difficult because of the purpose for biting - detain or drive off. In a pure fight drive dog, equipment seems to just be a kind of barrier to get around in order to bite the man. Fortunately, most working dogs have at least sufficient prey drive, so this is rarely a problem. Train the puppy in prey, and when he is ready, have the decoy invoke fight.
It should be noted that the bite in each drive has its own characteristics and are designed to overcome certain types of foes.
Prey Bite - full mouth, hard grip intended to catch, hold, and kill prey - often accompanied with shaking of the prey.. If the grip is not strong enough, the prey escapes and the dog goes hungry. Drive satisfaction is achieved through death of the prey.
Fight Bite - nearly full mouth, but generally not as full or hard as prey. However, the opposite of defense occures when the dog is pressed into intense combat - the bite deepens and becomes harder. The bite is designed to control or detain a foe until the rest of the pack arrives. The more you put it to him, the more he gives back. Drive satisfaction is victory and does not require a bite to fulfill.
Defense Bite - Generally full mouth with hard, intense grip often accompanied with growking or vocalization. The purpose of the bite is to survive. WHen the dog is really pressed in combat, the grip tends to be more shallow. The bite is more vicious and it goes against the dog's instincts to release the bite - it is therefore more difficult to control the dog. Drive satisfaction is survival.
It is clear the fight drive dog is the easiest to control, and the bark and hold is reliable because it is instinctual. Make no mistake, the fight drive dog's bite is more than adequate to take down and control a criminal - but it is generally not as showy as a prey bite in competition.
My last service dog was an excellent tracker because he had mega hunting drive. This dog tracked just to track. For police work all I had to do was give him the job of tracking man and let him discover the necessary pace. After that I just got out of his way and let him do what nature compelled him to do. He was absolutely reliable because of his instincts, not because of any training I gave him. The motivation for the hunt was certainly the chance for the confrontation at the end.
But, motivation to hunt is an exhausting subject on its own. Space, time, as well as fatigue prohibit me from discussing it at this time.
Brendan - It is to bad you did not attend one of the seminars I gave in Australia - most of your questions would have been answered. Kris Kotsopoulos and his group did video the seminars. You can contact him at
vonforell@vitel.com.au for info on the video. Otherwise you need to buy the book or come to one of my seminars. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
