There is an old adage that leashes serve as everything from birth control to good neighbor relations. Their use is mandated many places and most dog owners would never be without one, at least for emergencies. Deciding what the leash should be attached to is another matter.
A dog harness is a great option because it gives you multiple points of contact, distributing pressure from the leash to a greater surface area. It also relieves the sensitive neck structures from sudden impact which can cause injuries that are quite serious.
Harnesses come in such a wide variety of styles, it can be complicated to learn to use one. Since they can't be left on a dog when he's unattended, taking them off and putting them back on, should be simple. Materials are important for the comfort of the dog and ease of use. Shown in the picture are a bird harness by Premier, a mesh rabbit walker and a Thundershirt used to comfort anxious dogs. For regular dog walking, there are even more options.
