The document discusses the author's experience attending a clicker training expo with their service dog Penny. Some key points: - The author has 16 years of experience raising puppies but wanted more formal training in positive reinforcement/clicker training. - Attending the expo was beneficial for both the author and their partner to learn more about clicker training from experts. - They decided to bring Penny along even though she is still fearful since she is very attached to the author and unfamiliar places. The multi-day expo provided Penny with new experiences staying in a hotel and waiting to go outside.
