Walking your dog is good exercise for you and your dog. In the city, using a leash is recommended. People will be more comfortable, and your dog will be safer from cars and the possibility of being spooked and running off.
Off-leash walking is great when hiking outside of the city. Out in the wilderness, you and your dog can enjoy the beauty of nature. A dog’s sense of smell is 1,000 to 10,000 times greater than humans. Imagine how much he will enjoy going for a walk!
