Have you ever met somebody who enjoys being alone more than being with friends? I believe that deep down in their hearts, humans are all social beings. It is not natural for humans to be alone. Animals live in packs. If a dog lives with people, it seeks their company above anything else. Even if you are older and have a dog to keep you company, you might still feel lonely. You might want to learn about other older singles dating. A dog can never replace a relationship with another human being. While dogs are wonderful animals, they can never be a substitute for a healthy relationship with another person.
