Review on Premium Herm SPRENGER Pinch Collar-Small 12" x 2.25mm: Optimal Control and Comfort for Your Dog's Training by Robin Phipps

At first I was skeptical because of the good reviews on this product. I was amazed at how he transformed my naughty 2 year old Miniature Pinscher. I got it for free from Craigslist and didn't know how the previous owner trained it. Apparently the previous owner didn't have time to take him outside as he works a lot at night and sleeps most of the day. When we first went outside, he turned into a maniac and ran back and forth. Never stopped en route. It tugged at me because my arm hurt after a walk. Even when he's around other dogs, he barks and wants to start a fight. So ashamed. Then I saw it on the internet and bought it. To my surprise and delight, this has made him the most obedient dog I could wish for. Not minutes but seconds (I'm not kidding). I heard him squeak when he first tried to pull me, but I quickly learned. Whenever he tried to run in front of me and feel the "pink" he would back away and look at me like he was sorry (haha). Now my mother-in-law is willing to take him for a walk every day.
