If your dog is certified as a therapy dog, you can give back to your community by signing up to visit a nursing home or hospital. This is the perfect activity for courteous dogs because their calm and approachable nature has incredible healing and health benefits for others.
If your dog is courteous and calm in busy situations, take them with you to a local farmer's market. Dogs are usually allowed at these venues, but there are often lots of people and distractions. Your well-behaved dog will thrive in these markets and will simply enjoy calmly walking between booths and checking out fresh produce and local wares.
