I found it interesting when you mentioned giving the dog a job and making sure that the person is patient with it because they will not totally obey in the beginning as the act is very difficult for them.

During your sessions, be sure to wait a few minutes between absences. After each short separation, it’s important to make sure that your dog is completely relaxed before you leave again.
