I am truly happy for you though and do want to keep hearing the updates on your progress with her! I bet she's loving the attention and having to use her working brain! So not knocking you at all, I think it's great and you're doing great with her, just want to guide you in the right direction so you don't have to un-do any training, ya know.
Did you know that mental exercise is as tiring for dogs as physical exercise is? It's not a replacement for physical exercise, but having a dog that's a mix of two of the smartest and most high energy working breeds around, I had to learn that balancing mental exercise with physical exercise is the key to a happy and relaxed high energy dog! Brain games, training of any kind - along with strengthening your communication and bond with her - requires her to think and puzzle things out, and they thrive on the praise when they get it right! Helps tire them out the same way we get tired when learning something new that's a bit challenging or requires thinking hard and a lot of work.
Physical exercise still essential, of course. But some people get a border collie or a husky, walk them or even run them for hours, and cry "she's still so full of energy and destructive! Nothing is enough!" of course it isn't. A human can never compare to a dog in terms of endurance, they'll always outpace you, and these guys especially were bred to work for eight hours a day in rough conditions. You could exercise them eight hours a day, and they won't get more tired, they just get fitter! Balancing enough physical exercise with enough mental exercise is key for any dog, but especially with high energy working breeds and smart breeds.
