Great job Steven!
I see you got her up when she laid down:)!!
Looks like you guys have got it down!! Couple things I would adjust just a bit.
I wouldn't ask her to sit before the bark. I would try to keep her free if possible. If you do ask her to sit, continue marking as you are though, before moving on to the bark.
When you say yes and reward, I would back up to encourage her to be free and move around a bit while rewarding her. Do this instead of keeping her in the sit.
The barking itself is great. Great job getting multiple barks! She seems like a pretty great female, regardless of the breed.
Keep it up!!!
