After one and a half years owning Charlie, behavior classes, prong collar, getting 7 stitches over my eye from a fall, many sprained fingers from being pulled as well as pulled muscles in my back, neck and arms, Charlie responded well after 1 week with Bark Busters. Instead of running away from me 2-3 times a day because he is so strong, in 1 week he only ran away twice! I observed noticeable results after a few minutes! I have already recommended Bark Busters to my friends. Bark Busters is wonderful and saved Charlie from being sent back to La Mancha Rescue. Alan Croasdale is the best!
