Nikki is very thorough. We noticed results right away during the training exercises. We are very pleased with the Bark Busters natural techniques. We absolutely recommend Bark Busters to friends and neighbors. The Bark Busters method is intuitive and effective, once you learn from your therapist, how to COMMUNICATE with your dog. Nikki is a wonderful teacher. She takes adequate time to make sure you understand the method and is always available to answer any questions we may have we are learning how to be strong leaders for our dogs, thanks to her.
