I am experienced with dogs and all kind of behavior issues. I trained dogs in the military and now I train pets and service dogs. Any dog can be trained at any age. Also any behavioral problem can be fixed with the right methods. Aggression, nipping, jumping, licking, running out of the door, pulling on the leash, and many more can all be fixed. Whether your goal is Total off leash control or fixing a few behavioral problem they can be achieved so your dog can be a loyal life companion who you can take anywhere with you. I live in delaware county. Hope I can help you and your dog have a happy balanced relationship!
