Wow! Bobby is a new dog and after only one day! He is a 7 month old Cavalier King Charles spaniel that is being trained as a Medic Alert Dog for our 7-year-old son. Bobby had two trainers before Patrick came to our home. We didn't use choke collars or other painful methods. Bobby always walked us and he would run out of the door of our house when it was left open by one of our three children. We are now in control; Bobby follows us when we walk him, he does not run out of the door, he sits, stays and does everything he is asked to. I know Patrick explained how this worked but until you have seen it you just can't believe it!!! And knowing Patrick is there if I get stuck on more advanced training is terrific!! Thank you Thank you Thank you, Patrick and Bark Busters!!
