I have a 10 lbs small dog. He was a puller from the day I met him. Treating and positive training was going about 50 / 50. A friend suggested this in a small / petite and our walks were a million times better in the first go!On day 2 of walking, I was remarking what a great walk we were having and how he wasn't pulling and that this halter was amazing. I looked down and noticed that I have actually clipped my leash to his collar, not the halter.In ONE walk my dog because a non pulling, obedient walker, allowing me to take the lead. I am a convert and will tell everyone about this.
