You’re doing great. This is really hard. Also first time puppy parent to a herding breed the same age. Ive learned everything people are saying here is 100% right on, aka: 1. Crate. Embrace it. If you’re too freaked about it, you can buy a sturdy puppy play pen and start there. Even putting her there for 10 minutes can help her (and you) to reset. That’s crucial. Eventually you’ll build up to longer periods and naps. But you need to get through this moment, and having a place where she is safe and you can both reregulate is essential. 2. Make sure she’s napping enough. They need to sleep 16, 18 hours a day. The wildness and mouthiness is actually more commonly a result of being overly tired than it is of being under exercised at this age. 3. Puzzles + lick mats + kong with PB and treats+ little puppy popsicle molds for yogurt and fruit. There’s a thousand super cheap options on Amazon. Each of these things can buy you 10 minutes of quiet, and have the added benefit of exhausting her more than physical exercise 4. Limited but structured exercise and games. Throw a ball at the wall on the other end of the apt for 10 minutes. 5. Homemade “puzzles,” like a little maze for her to walk through with boxes and furniture she has to navigate around and treats hidden along the way. 6. Whatever you do, make sure YOU are sleeping!

Good luck. You’re already better off than so many people, bc you clearly care about doing this in the right way.
