I was amazed at this video. This is the best example I have ever seen of an Alpha owner. You can tell how physically and mentally these dogs are stimulated and how healthy and happy they are YouTube - freerunning sleddogs
Im amazed. What a fantastic dog owner. Those dogs were completely under his control. I love how happy they all look and as you said mentally stimulated. He obviously adores each of those dogs and they look to completely adore him.
