Whether you need a large dog harness or something flashy for your dog, there are many good choices. Your pet harness should be purchased with the desired purpose and your dog's breed in mind. All dog collars and dog harnesses are only tools, you have to find the one that is right for your dog. But for a normal dog, a harness can be a safe and effective training device.
Using a strong dog harness for walking large active dogs may seem difficult but many modern harnesses feature basic but clever techniques like the front-attachment rings. When a dog lunges, it causes a slight tightening or pressure across the chest and behind the legs. These gentle but odd feelings cease when the dog stops pulling or lunging.
Combined with positive reinforcement, most dogs quickly associate pulling with unpleasant sensations. If your goal is to train a strong dog that pulls and lunges on a leash, look for a training harness with a martingale-type closure that tightens in response to pulling and loosens up when the dog stops and the leash relaxes.
If your dog likes to swim, or you live in a rainy, humid climate, you'll want a long-lasting nylon harness. For a well-behaved dog that doesn't get wet very often, leather is an elegant, long-lasting choice. A reflective harness and leash set should be considered if you and your dog walk at night. Whatever the choice, harness training, like all training, requires consistency and patience. Most owners who try harness training experience satisfactory results.
