What are the 'better' products for dogs/puppies to use?

Harnesses for dogs are kinder for walking your dog that the standard dog collar and leash method, as most dogs pull at some time or other, which can cause wheezing, coughing and sometimes trachea and spine injuries if the dog has the leash attached to a collar. A dog harness spreads the pressure across the chest evenly and prevents injuries. One of the best anti-pull harnesses to use as an aid to train your dog not to pull, in my experience,is the Premier Easy Walk harness with the front D ring. The harness is often called a Gentle Leader - like the one you mention.
