After working with Donald Cohen and Bark Busters, our dog Daisy is a different dog. She is calmer and better behaved. It is rewarding to see the natural training techniques that Donald showed us how to use. His knowledge and the way he explained things were truly helpful. The training is sometimes a challenge because our dog tries to test us, but when we remember to remain calm and patient as we were shown, it works well. We would recommend Bark Busters, if you are willing to put in a little time and follow what they teach you. Like we said, Daisy is a different dog. Thank you!
