Lennox Gavin has a heart of GOLD and the know how to teach you how to teach your dog! His calm manner is wonderful. He makes it appear so easy. Redwood, my yellow Shep mix was one crazy doggoing in circles, jumping on everything..totally out of control. After the Obedience Training with Lennox he now knows sit/down/stay/roll over and walks great on a leash. His wild personality is now focused and he listens when asked to do something. He really seems to enjoy the traing.Redwood is happier and so am I. I highly recommend Lennox.. He is a treasue!!!!
