I put the leash back on and sat her in front of a jump. I took a lead out in front of the jump and came back to reward her several times. I also tried releasing her to her toy at the start line from her sit stay. Then I took the leash off. I left her on a sit stay in front of the jump. I went back to reward her for holding a sit a few times and then released her over the jump.
We'll try some more of this later.
