UPDATE!!! Luma did the Sit command many times today!!!! She had just woken up from a nap so she wasn't hyper yet, I used some liver treats and a clicker and she just did it over and over and over! I'm soooo happy lol
She sometimes confused sit for "down" and would just go all the way down but that's better than nothing! Now she's too hyper to keep going, but just wanted to share our progress. Gonna try to record a video of it soon.
