Today Mia had her very first off-leash workout. She was still inside the fence but she did well. There was only one time when she ignored me and went to the door instead of coming when called. Everything else she did well with little reminders here and there. Tomorrow I am going to take her to the farm for more work but it is still a little premature to take the leash off without a fence, I think.
All in all, a very good second day.
