Why does dog wear harness?

Dogs use harnesses for safety. A Collar is great to attach your dog tags to so people can know who the dog belongs to but a harness attempts to alleviate the strain on your doggies neck when they still pull during a walk. A harness is a great idea if you have a strong dog and love to show them off. The harness will keep your dog secure in any situation and most importantly keep your dog from hurting itself when pulling. I use a nylon 550 paracord harness for my dog. It is flat, safe and comfortable.
