I am really interested in finding out how positive trainers deal with aggressive dogs. Some of you may know about Katya already. She is a six-year-old Caucasian Ovcharka, (very basic breed info can be found here http://www.i-love-dogs.com/dog-breeds/Caucasian-Mountain-Dog.html) Basic background. Katya was in obedience training at a very young age. She is very responsive to commands in certain situations, excluding ones that include suspicious people/animals. She is well mannered with her family and those she knows. She is not play motivated and has very little intrest in food rewards. Katya has been raised by my mom for the majority of her life. While under my mom's care Katya has bitten four people and consistently aggressed moving vehicles, bikes, adults, children, other animals. While under my care for over a year I never once had a problem with aggression, she was properly introduced to people and other pets on my terms. When she first met someone new and would aggress she was given a verbal correction first and if that was not enough she was given a collar correction on a buckle collar(we always use a prong on walks for everyone elses safety). If that still was not enough she was placed into a seperate room for the visitors safety. Question. How do you positive trainers teach a dog proper behavior without corrections when the dog has no interest in rewards during their high payoff behavior of lunging and aggressing? Desensitization has been attempted but under the right circumstances (everyday run in's on walks, etc.) no matter the length of time the dog has been allowed to become desensitized (honestly tried for months) the behavior continues. When Katya goes into guard mode there is no stopping her with treats/reward, she has absoulutly no interest in anything except getting to the perceived threat. During Katya's time here she went on daily walks with me, whenever I saw a person approaching us we stepped off the walk to the side, issued a sit command and made sure she was not looking at the person. If she aggressed she was given a firm correction with the leash. Within two weeks time she ceased to exhibit aggression on walks at any person or moving object. Now she is back with my mom, next door to me. We walk all four dogs daily for approximately 2-4 miles. My mom uses Cesar's methods of implementing exercise, correct discipline, and then affection. This has been working well for her and she is finally confident enough to walk Katya on her own (took about six months). We both are honestly curious to hear how a NRM and only positive enforcement would be used with a dog of this caliber with no interest in rewards. How would you initially approach the dog and what type of response would you issue when the dog lunged, ready to attack? How long of a desensitization period would you use to condition the dog not to aggress every moving object/person. How would you build up to the moment of the introduction, keeping in mind everyones safety? I would really appreciate a breakdown of the methods you would use in this type of situation. I have been planning to try some new methods even though the ones I used with her were successful to a degree that she is not a threat anymore. This thread is not intended to spark any arguments or debates, I am all for using whatever techniques work for you and your dog. I am just really interested in having the techniques broken down so I can attempt a new angle with her training.
