One thing all dog owners should do is walk their dogs everyday in their neighborhood using the SAME route every time. You want the dog to become familiar with all of the sights and smells of this route. If their dog ever gets loose it is likely going to be found somewhere along this same route so this will help it’s owner find it in most cases. In addition, folks living along the route get familiar with seeing the dog and it’s owner so it raises a red flag with them to see the dog out and about by itself. They are more likely to help the dog reunite with it’s owner.
Lots of folks drive down to the park to walk their dogs or drive somewhere away from their neighborhoods to do so but I recommend this neighborhood approach for the reasons I have stated above.
