I will definitely respond to those questions tonight.
Zucca and I have been improving. She is showing more enthusiasm with high value treats like chicken or turkey treats. Also, it really helps to have a continuous flow to the box session by throwing a treat to the side and avoiding commands for her to come/sit/etc.
Without much pushing, she is also moving toward active alerts by pawing at the box and then sitting for her treat. I will continue using those alerts that she has basically implemented on her own.
I hope to post some longer videos of our sessions this weekend including several from these areas posted above.
p.s. You may not recognize Zucca in the next session because she got her summer cut last week and is a whole new pup! She seems to enjoy life with less hair given our recent warm weather.
