Can a dog provide instant relief with no side effects?

Here’s a little something I found in my archives. I didn’t write it so I can’t take credit ( or blame 😊) for its content:
Why is a dog such a great therapist?
                  1-You can babble on endlessly and he won’t interrupt you.
                 2-He never gives you needless advice.
                 3-He’s always providing positive feedback.
                 4-He doesn’t fake his interest in you.
                 5-He’s not in it for the money; he’ll settle for kibble.
                6- He makes sure every session ends on a positive note.
                7-He never violates your confidentiality.
                8-His nurturing skills are unparalleled.
                9-Scheduling appointments is a breeze.
               10-He never double-books appointments.
               11- A dog helps you break life down into its simplest and best parts.
               12-He is on 24-hour call for any emotional emergency.
           13-Minutes into watching your dog at rest or play  you forget what was worrying you; try that                with a human therapist.
