How many know of a dog tied that is in an area where it can smell and hear people and other dogs, but can't see them. Now that is very frustrating, worse than prison. If they must be tied, make it as enjoyable as possible. A dog at the end of a rope or confined to a house should be taken on walks and allowed to run free sometimes. One of the main benefits to having a dog is that it forces you to get out on walks, get exercise.
Dogs are so thankful to get out.
They are enthusiastic and happy. It can help make your day. A bove everything else, dogs are interested in other dogs. Second, other animals, third food, and so on. While living in Phoenix, I had a choice to walk my dog in a desert preserve, or on an empty lot where other dogs had defecated and people had thrown trash.
