Dog Bite Training is a minor component of formal German Shepherd Schutzhund Training (rarely of the morphed Schutzhund Dog Sport). Dog Bite Training also is a (more significant) component of German Shepherd Protection Training. Finally, some individual dog owners undertake their own Dog Bite Training (and not only those with a criminal background).
German Shepherd Dog Bite Training
Unless you are a studied and experienced Dog Bite Trainer, we would strongly advise you against undertaking your own Dog Bite Training. Because if not done right then your bite training will promote not only the reactive bite but also the proactive bite.
Genuine, skilled Dog Bite Training is organized and executed in a way that the dog perfects the Defense bite - which is a reactive bite - and that the training reduces bite temptation for all forms of the proactive bite. This is done not only for reasons of public safety but also for insurance reasons: If the dog liability insurer (or homeowner's insurer) has the slightest suspicion that the dog may have been trained to bite proactively, then any future bite incident will not be covered by the insurer (in addition to the dog likely being put down).
Before an insurer is going to pay out a high sum for damages to the victim, the claim adjuster will investigate in your neighborhood (and today via online sources like email, social media etc) if anyone knows of your dog having been trained to bite. And if the adjuster can substantiate his suspicion, the insurer will refuse to pay out. In such case the dog owner will have to pay for all legal cost and damages to the victim (including income loss).
So, undertaking your own Dog Bite Training rarely is a sensible decision, particularly today where via internet everyone can find out everything about everyone else.
Now, if you're still reading here, you must be either very determined or very interested.
Dog Bite Training - Standard Process
When your German Shepherd is being professionally bite trained, the dog trainer's handler will use protective armour and repeatedly simulate a controlled attack with a stick in an observed environment. The dog is then gradually being trained for full force mouth bites into the handler's protected forearm, to hold on to the attacker even when the attacker tries to shake off the dog, and not to loosen the bite until the trainer shouts OUT!
- protective armour
- controlled attack
- with a stick
- observed environment
- bite into the protected forearm only
- until the trainer shouts OUT!
All these terms clearly mark the enormous differences to genuine German Shepherd Protection Training!
Also note that Dog Bite Training as described above will not start before your German Shepherd has proven to the trainer that the dog fully and instantly complies with all relevant dog commands during prior dog training sessions.
In summary: Dog Bite Training should always be left to professionals. If you can't afford a professional Dog Bite Trainer, don't do it. Instead, go play with your dog. That will improve the relationship, and the better your relationship with your dog, the more likely that your dog will go out of his/her way to protect you, should such need arise. Obviously this doesn't mean that your dog will be skilled to protect you, yet be aware that there are far more important skills of a Protection Dog than to bite.
We don't get paid for saying "leave it to professionals", it's just common sense. Even if you've watched 20 hours of dog bite training video and you've read 5 books on the topic, that doesn't make you a skilled Dog Bite Trainer, sorry.
