Most harnesses choke. That's a design problem.
If your dog still yanks you down the block, it's probably not "training." It's the harness.
Cheap harnesses load the throat. The dog panics, pulls harder, and you both hate the walk. I've watched that loop for years.
The no-pull design we sell puts the force on the chest and redirects it. Front D-ring, padded, reflective, name patch so you're not jingling tags at 6am. Fits 4 lb to 140 lb.
Not magic. Just engineering that doesn't punish the dog.
If walks have been a fight, start there.
