1、No-pull harness

No-pull harnesses rely on a level of discomfort, force, and avoidance to alter the dog's behavior. When the dog pulls, a strap within the harness tightens. applying pressure on the dog's body which the dog must actively alter the pulling behavior to avoid. If the dog pulls, the leash goes off to the side and directs the dog back towards the owner. That gives a greater ability to control and guide the dog by applying a little pressure.

2、Chest harness

The chest harness is fastened to the dog’s body with a chest strap and a girth strap. The chest strap extends horizontally at the level of the sternum, between the two shoulder joints. The chest harness is available in both saddle and non-saddle versions. This type of harness is easy to put on. The materials used are straps with leather, nylon, or even polar or neoprene lining. This type of harness originates from ancient China, its first depictions of draft animals date back to around 150 B.C. Wandering, conquering peoples, such as the Avars, Huns, and Hungarians, played a major role in its spread in Europe. It is still used on horses to drive carriages on normal, light terrain. A beautiful example of this is the four-horse statue on top of the Brandenburg Gate in Berlin. Nowadays, among horse riders, the chest harness is the most used in the field of coachman leisure activities due to its simplicity.  It is less suitable for pulling heavy loads, as the bearing area of the strap is smaller than that of “hames” harnesses. In the case of pulling a load, the chest harness is less effective than hames (Y-shaped) harnesses because the strength of the dog’s muscles near the spine and hind legs is not effectively utilized. As a result, the chest harness is not used at all in pulling sports that involve dogs. The benefits of the harness type are very noticeable in everyday, urban use, and they are also often used in the world of service dogs. By using a harness that keeps the neck area free when the dog is pulling on the leash or needs to be pulled back you can avoid putting pressure on the trachea, which restricts breathing and can cause a tracheal collapse in the case of dogs that are prone to it. To prevent this, the chest harness serves as an alternative to the collar, which is essential for dogs prone to tracheal collapse.

3、Y-harness

The straps of the Y-harness are located between the neck and shoulder joints and surround the dog’s neck. This makes optimal use of the animal's pulling power. Due to its structure, it is more complicated to put on and take off than chest harnesses.

4、Sled dog harness

Harnesses are used by sled dogs for running, cycling, sledding, skijoring, or pulling weight. There are several different types of harnesses available for sled dogs. Some common harness types Are x-back, H-back, half-harness, and spreader bar harness. The X-back style harness is the typical choice for recreational and sprint/mid-distance mushers, due to their lightweight and durable make, ease of accessibility and fit customization, as well as the speed at which they can be put on and taken off dogs. Half-harnesses are believed by some mushers to result in fewer athletic injuries and are used by some long-distance mushers in place of the traditional X-back. A harness with a thicker lining and a wider chest strap is preferred for pulling heavy weights. They feature more overall padding and extend further behind the dog (no more than 24 inches from the base of the tail in weight-pull competition).It has been designed to help the dog pull heavier loads safely and efficiently, and may feature a spreader bar behind the wheel dogs and in front of the sled or cart. These harnesses help distribute the weight of the cargo over a broader area of the body.

5、Rehabilitation and lifting harness

There are several types of rehabilitation or dog lifting harnesses depending on which parts of the dog's body need help. It is a harness with at least one handle that wraps around a dog's body to allow a person to help lift the weight off of their hips, spine, or legs. There are several different types of them available, each of them providing its own unique advantages. They include front harnesses, rear harnesses, front and rear combo, mid-section support harnesses, amputee harnesses, and full-body harnesses. There are several conditions that may make it necessary or at least helpful to use a dog lifting harness, some of the most common being: hip dysplasia, broken bones, sprained knees, spine injuries, arthritis, recent surgery, strained muscles, and missing limbs.

6、Tactical dog harness

A tactical dog vest or harness provides an extra layer of protection that is needed. Most tactical dog vests are provided with a handle to help the dog on difficult terrain. It can also be used to hold additional devices, such as a GPS tracker or a light. Further specialization is possible depending on needs: bulletproof; suitable for descent; mantraili

ng harness, etc.

7、Assistance dog harness

Assistance dogs typically wear a vest, cape, or harness for identification. The gear is often utilized during the dog's work. Cape harnesses are ergonomic and well-made. Usually, there is ample space for identification patches. The pulling harnesses are worn by service dogs who need to pull heavyweight. Pulling harnesses are usually padded for comfort. Mobility support harnesses are for assistance dogs who need to pull their owners. They are ergonomic and have a rigid handle.

8、Car safety harnesses

Safety harnesses were designed to restrain the animal in a car seat using the car's seat belt. In the event of an accident, the harness distributes the pulling force. Several car safety harnesses have been designed that pass crash tests conducted in the USA by the Center for Pet Safety.
