Function

• Harness training replaces the use of a regular dog collar for walking a dog. An excited dog without walking training will pull on the collar and leash, potentially choking himself in the process. Dog harnesses cross the chest and wrap around the midsection of the body, providing a snug and comfortable fit without a risk of choking the dog, especially during training.
  
  

Types

• Dog harnesses come in different materials, sizes and types depending on the breed and the intended fit. Some specialty harnesses exist that provide additional benefits, such as the Gentle Leader or Halti harnesses, which are designed specifically to prevent a dog from pulling unnecessarily on its leash. There are also generic-style harnesses that are made from the same nylon materials as collars, but fit more comfortably on the dog, placing pressure mainly across the chest rather than the throat.
  
  

Considerations

• It is important to properly fit a harness when training your dog to walk using one. The harness needs to be comfortable, which means that when it is placed on the dog, you should be able to get two fingers between the dog's skin and the harness at all points, including across the chest, back and belly. This ensures that the harness is not digging into the skin or cutting off circulation anywhere on the body. A proper fit is necessary if you want the dog to be receptive to your training.
  
  

Training Process

• A well-trained dog will walk alongside his owner, with slack in the leash, rather than pulling excitedly. The training process is not difficult, but does require patience and time. Fit the harness properly, and work with a short leash. When the dog pulls excitedly, give the leash a quick, sharp tug. This will let the dog know he needs to slow down. Repeat this process with each time he pulls until he walks with you rather than pulling ahead of you. The nature of the harness makes the quick tugs safe for the dog--and yet, still effective.
  
  

Expert Insight

• "If you are having trouble training your dog to walk with you, consult your veterinarian or a local dog obedience trainer for advice," says Caroline Tanaka, a licensed veterinarian. "There are a myriad of different training devices that you can employ; you simply have to find the right one that works for the individual dynamic between you and your dog."
