For many dogs, a harness is a great option over a collar when training, walking, hiking & traveling. Dog harnesses distribute pressure evenly around the chest area when a dog pulls instead of around the neck, which could injure the trachea. A dog harness provides you more leverage and is very useful in training puppies not to pull. Dog harnesses also can double as a safety harness for traveling. There are many styles of harnesses to choose from, including a padded harness for dogs, restraining harness, walking harness, climbing harness for dogs, or a pulling harness.
