I heard about Willie from a friend of mine who only knew of him by reputation. I can honestly say what an amazing trainer Willie is and his co-worker. I had already decided that I was going to do my rottweiler puppies training the old fashion way, me, doing the work with the trainer and not leaving my pet for them to do all the work. It has been a labor of love. Harley adores Willie and at 7 weeks old she was already placing, sitting and knew her name. She is 5 months old and will sit, lie down, place, come when called all off leash with no collar. Willie is an amazing trainer and regardless if you leave your pet or they come to you, you will not be disappointed.
