Thor is being asked to walk with me and follow. He has learned this behavior thru luring exercises,and walking with my other two dogs matching their pace and behaviors. It is somewhat of a monkey see -monkey do process,if the other two dogs sit when I stop he matches their behavior and is rewarded for it. If you think about it dogs learn in pack structure by obseving the older more experienced dogs. If I ask my dogs to sit, they immediately do, he then matches their behavior ,learning quickly what sit means.
