Dogs are a man's best friend, but can dogs really be buds with a dolphin, a deer, a bear, a cheetah and a donkey? Ben, a Labrador Retriever, meets an underwater friend, Duggie the dolphin, and often swims to the point of exhaustion to hang out with him. What happens when Ben gets too tired to make it back to shore? Duggie gives him a lift, of course! Cesar Millan joins this episode to explain why it's perfectly normal for a pup to pal around with species of all types - even unlikely wild ones!
