Five men (A,B,C,D,E) and their dogs (a,b,c,d,e) went hiking. They want to cross a river that was deep and swift. One boat was there. Using that boat you can cross the river. But the problem is the boat capacity is taking only three living things at a time. The Dogs were edgy and couldn't be near another person (not even momentarily) unless its owner was present. One of the dog is highly specialized obedience school and therefore knew how to operate the boat---the other dogs lack this skill. How did the men and dogs cross the river?
