it does wonders when your babies are happy, seems pups are doing great, am sure you feeling relieved! And I bet classes will do wonders for your gang, they sure making big difference for mine.
The only thing I would caution you from what you described, about using spray water bottle for barking. I use it ONCE and Che started lunging and bark even more at ANY sound of spray, grooming became nightmare and it took me FOREVER to counter conditioning it. VERY BAD advice, often given.
Outside if barking starts, U turn on GL , get enough distance, ask for behavior or tug, if not enough go back some more etc.
If my boys bark at something in the house like someone walking past the window- they just lost their privilege to be near that window, off the go in another room or on leash and get to spend some quality time on the mat with me. While timeout is still a punishment, it is more useful specially if you combine it with learning positive behavior for this situation as opposed to suppressing barking with water spray.
