Henry is practicing the first steps of loose leash walking. He's wearing his new Freedom harness which makes it a lot easier on his body when he does pull. There is no pressure on his neck as there would be walking with the leash attached to the collar.

Harnesses do not teach your dog to walk politely but they do make it more comfortable for the dog as they learn to walk without pulling.

As with any skill, reinforcing your dog for what you want is key.
