<human>: Can you provide a brief overview of the text?

I have recently cranked up the training I've been doing with my dog. She's a pain to walk and I want to clean up that behavior, I recently moved to a new place and want to train some specific behaviors for the new place, and I want to get her GCC cert sometime. So, lots of new things for her to learn! 

I want to train her without over training, confusing, or exhausting her. 

I've noticed that after a training session, especially one involving a new or newish behavior, she tends to flop out and go into a deep sleep. I suspect this is an important part of the learning process and try to leave her alone when this happens. On the flip side, she's a smart dog and if training is too repetitive and easy she gets restive and starts looking for shortcuts and loopholes (like doing the first half of a behavior rather than the whole thing).

Each dog probably has their own optimal training schedule that balances hard enough to be interesting with easy enough to not be overwhelming. I struggle with figuring out this balance for my dog--how do you guys figure it out for yours?

<bot>: I know everyone just has to learn their dog by trial and error, I'm just looking to share stories and general ideas.
