Malakai said it well. I'll add some general advice to that.
Two things that were drilled into me when I started training working dogs:
- Whenever you are with your dog, one of you is training the other. You have to make the conscious decision to be the one doing the training and not being trained.
- Everything you do with your dog is a training opportunity.
I sometimes let my dogs train me to do things if it is something that makes them happy and won't interfere with obedience, behavior, working needs. #2 lets me accomplish a lot of training throughout the day in the normal course of events, especially once I have the basics like sit, a short stay, etc. Eventually it got to the point where I do these things without thinking about them.
I firmly believe in giving my dogs choice whenever I can. In regard to training, this means that I may go into a focused session thinking I'm going to work on one thing, but the dog tells me she would prefer to work on something else, so I'll switch to that. By doing this we'll progress faster on that particular thing because she wants to do it and had a say in it.
One thing I do throughout my dog's life is have "dog time" at least once a week. I do this outside at home and also go to areas where there won't be other people and dogs and are safe for my dog to be off lead. For this I simply sit quietly and watch my dog. Engagement is up to her - both if we engage and how we engage. It's a time for her to be a dog and for me to observe and contemplate. You can learn a lot about your dog and strengthen your bond by doing this.
When it comes to training, sometimes less is more and more is less. What this means is that if your dog does so well on on a rep that it can't possibly do better at that stage, stop right there and avoid the temptation to do one more. Even if it's the first rep. When you get that rep that is as good as your dog can do at that stage, give a huge reward with lots of praise, and then the dog has quiet time for an hour. A huge reward with lots of praise will release endorphins and the dog will ride the endorphin high for an hour. If they have quiet time while riding the high, they will spend that time thinking about what they did to get that and processing what they just learned. This means the knowledge sticks in their brain better and learning becomes more efficient. There's a bunch of science behind this and I see it in my SAR work. The handlers that practice this have better dogs that progress more quickly than the dogs of handlers who always want to do one more problem and think that they need to be working their dog constantly.
