Input: Update: we continued trying to use it, only on walks (and she's usually a yard dog) for about three weeks. Today the front chest section ripped almost clear through and she got away from me at the vet. When i posted my initial negative review, i got an email from the seller asking me to either make or positive or remove it. It was poorly translated to English and was rude. They implied that I measured the dog wrong, and then told me to go to the two clip version, which their site says is old but their email says is new. Don't waste your money. I was excited to try this after reading the reviews. It is well-made, seems durable, and is reflective. The sizing chart is awful; i have it cinched ALL the way down small and it's just barely tight enough. I don't understand the "magic" everyone else seems to have discovered as far as this getting their dogs to walk without pulling when all else had failed. I have a 1.5 year old female boxer mix, about 65lbs. I don't think there's a harness or training technique we haven't tried to get her to behave on a walk. This was no different. She yanked the same as ever and got the harness twisted around her so that the top and bottom became the sides. While this seems to be made well, it's still entirely useless.

Tore in 3 weeks, never helped with pulling, sized terribly
