A dog harness is a device that fits around a dog's body and provides a more comfortable and secure way to control and guide the dog during walks or other activities. unlike a collar, which can put pressure on the dog's neck, a harness distributes the pressure evenly across the dog's chest and back. this helps prevent choking and injury and makes it easier to control the dog, especially if the dog pulls or lunges. dog harnesses come in various types, including front-clip, back-clip, and no-pull. front-clip harnesses have a ring on the front of the chest, which can help prevent pulling by redirecting the dog's attention toward the owner. back-clip harnesses have a ring on the back, which is useful for dogs that do not pull and need minimal control. no-pull harnesses are designed to discourage pulling by applying gentle pressure to the dog's chest or armpits. dog harnesses are available in different materials, such as nylon, leather, and mesh, and are adjustable to ensure a comfortable fit for the dog. some harnesses come with reflective strips or stitching for better visibility in low light conditions, while padded designs offer additional comfort and reduce pressure points. some harnesses also have a handle for better control in certain situations.
