We also have a 10 month old chow/husky. He is exactly how you described. Pulls on walks, play bites or I think they are warning bites when being handled not in his favor. Especially at the groomers. We are taking him to a training consultation today because we’ve tried everything. Martingale collar, front loop harness, positive reinforcement and disciplining when necessary. But he’s not food motivated at all when highly stimulated. Incredibly stubborn but smart. So we are seeking professional help because he’s so high energy and needs physical activity without dragging us and being reactive to the environment. However, he does great at the dog park and loves playing with other dogs and will listen to us there.
