One major progress that Skye has made is on the time it takes her to bounce back from a stressful event.
Here you can see her flinching from the touch of the leash (it was my first attempt of adding touch to our leash training). Instead of walking away and disengaging from the training, she is able to continue right away.
Similarly here, she wasn't comfortable with me dragging the leash on the ground (a new training exercise) but continued working with me as I carried the leash instead.
