I was very happy with how quickly she worked and found the hides. On the first one, I wanted to reward the hunt (vs the find), so I told her "yes" as soon as she got to source, even though she hadn't pinpointed it for me (she was an inch or so past when I said "yes"). The other two, I waited for her to pinpoint.
On hide #3, the lawn, I purposefully started us far back to make the hunt a larger portion of her work. She already had odor when I told her to 'show me,' and we were about 30-35yds from the hide.
3hrs was a bit long to age them, for where she is in training. 1-1.5hrs would have been more ideal. However, this is how life runs, and so we work with what we have. :)
