Best thing I ever bought for my dog!!!! He used to pull so much until I bought this harness. It was recommended to me by my trainer! Since the D ring at the front, once they pull, they are being led back which corrects them. It’s seriously the best investment ever! They also have great warranty but I’ve never had to use it and I’ve had mine for 3.5 years now! 10/10 #furryfriends
