"Thanks Dave for helping me with our dog, Izzy, the Pitbull. I have been trying to take her on walks for 3 years now. Her pulling made it very difficult to enjoy a walk. I gave up because she is so strong - she would walk me. I must admit, I'm a little jealous. You came over to our home and had her walking beside you in 5 minutes. Looking forward to working with you again. Thanks! Corrine "
