Review on 🐶 Premium ShakeTrainer: The Complete Humane Dog Training Kit with 5-Minute Instructional Video - Effective Solution to Stop Your Dog's Bad Behaviors in Minutes, No Shocking or Spraying - User-Friendly and SEO-Optimized by Jennifer Addison

I have a crazy, naughty, vicious, grumpy, outspoken, stubborn Cairn Terrier, Fergus, who has been terrorizing our sweet, quiet, tame, medium sized Cairn Terrier, Milo, for the past six years. We bought Stop That! Spray that works from time to time. I bought this, watched the video and immediately introduced Fergus to this shake trainer after letting Milo out. The changes in Fergus are amazing. It was instant and lasted over an hour. One day he started growling at Milo. A shake and he stopped growling at him immediately. Fergus is always insanely jealous of Milo when he gets attention and my husband could pet and talk to Milo in front of Fergus who sat quietly and watched. I highly recommend this product! The difference was phenomenal! Worth every penny and more!
