WOW!!! My husband and I are so excited about our experience with Marsha this afternoon. Our 1 y.o. Plott Hound mix was showing sings of aggression and then bit my sister-in-law last week. Needless to say we were distraught! We called Bark Busters and were impressed right away with the initial contact and reassurance we were given that the training we would receive would work for Comet. I have to say I was anxious and skeptical and couldn't figure out how they could help us-BOY WAS I WRONG!!! Marsha was great, both with teaching us the techniques, but also with answering our multitude of questions. Comet is responding already, even since Marsha has left us to work on our techniques. He is learning, rather quickly, that my husband and I are the leaders of the pack, which is making all the difference. I am excited to keep working the steps we were taught and improve Comets behavior! Believe the hype, this is by far the best investment we've made for Comet, and Marsha is our hero!!!!
