Dogs are good listeners. Very receptive and not sat all critical. They will pretty much wag their tale at anything you say, depending on your tone of voice, of course. The family pet can be a great first audience for your ‘so, tell me a bit about yourself’ story. Try out your first draft on them….tell them the complete and unvarnished truth about yourself. Confide your weaknesses. Tell them your fears. Your dog will gaze at you adoringly.
Be sure to work on your "so, tell me a bit about yourself" (tellmeabit.com) and polish it up before you tell a bit about yourself to someone other than your dog.
