. . . I've gotten some mixed advice from my breeder, various trainers(helpers) and videos . . .
I smiled when I saw these words, because they so accurately describe what we went through when we first started schutzhund. What's that saying? Put three trainers together in a room, and the only thing any two of them can agree on is that the third one is doing it all wrong.
I guarantee that you will continue to get conflicting advice, and you may find this very frustrating at times. But in the end, this is a good thing, because as you become more attuned to your pup's personality and her strengths and weaknesses, it will give you an array of options and approaches to choose among. Every dog is different and what works with one dog may not work with another.
At one point, we were so frustrated that we ended up appealing for advice to a friend who is a trainer and who had just qualified her young dog in SAR. Her advice? Just remember that Jack is your dog and you know him best. You know what your goals are for him, and the path you choose should help you achieve these goals.
I'll just add that, in retrospect, there are a few things we would probably do differently with another puppy.
The first is that we would be much more conscientious about being prepared so that we could redirect him when he did crazy and annoying puppy stuff (and believe me, he did a LOT of crazy and annoying puppy stuff). We would make sure that we always carried a tug or a ball so that we were never caught empty-handed.
The second is that we would be more patient and not try to bring along his formal obedience so quickly. We would spend much more time on play that is fun and that focuses on us as the source of the fun.
And finally, we would have more confidence in our own instincts and abilities. Though we were far from new to dogs, we were new to the sport and we did pretty much as instructed, especially at first. Having now gained some insights into the sport and having seen positive changes to training strategies, as well as an array of training strategies, we would be much more comfortable and relaxed about working out the best techniques for our particular dog.
Good luck with your girl. You have an interesting journey ahead.
