Sorry! Cricket is another dog (on my brain, apologies- I was just watching her videos with a very similar thing going on)
For now it is okay if she sees you hiding targets but eventually we want to remove that aid for Daisy. So eventually you will want to put her out of eyesight.
As for shaping your pawing alert- I would say keep doing what you are doing, but about every 2 out of 5 times, wait a second or two and see if you can get that paw alert. If she does offer that, jackpot her for it so it becomes solidified that this is preferable to just smelling. A nose target is great as well, as eventually you’d like her to be able to do both.
If you haven’t gotten to that point in the lessons yet, read through the material- we go over how to shape and refine an alert.
