Linda was so easy to understand and she was so patient with our confusion. Both Novus & Potter responded remarkably quickly. I was very pleased and the bags aren't used very much any more. The Bah alone is effective. The training was very intense . . . but so very worthwhile! I have already recommended Bark Busters. Even though it is expensive, it is worth the effort and time. I have spread the positive word to Oregon Vet Clinic! It is just necessary to work daily and I find that my key issue is over our busy life. I will continue to try to be organized and committed!
