When I visited my dear friend Linda, I met her adopted dog Gabriel. We took him to a very large dog park in Seattle where dogs who enjoy the water can take a swim. There were many at the park that day. The dogs are not leashed. As we walked, Gabriel would do his own thing: he smelled other dogs, explored the grounds, and ran. He always stopped and checked where we were, and he stayed within eye view. We walked for a long time.
When we got home, Gabriel took a nap. End of story.
