Like humans, dolphins exhibit empathy and altruism and they even mourn their dead. And it's not just emotional or intellectual traits that prove how intelligent they are. Their brains are also quite large. Their brain size compared to their body size is second only to humans. The most wonderful fact is their helping tendency and there are many examples of it. They help other animals who fall in danger.
An amazing and unbelievable incident happened in  Marco Island, Florida where a dolphin came to the aid of a lost dog that had fallen into sea. The dolphin noticed the dog was fighting for floating on water who then rescued the dog. The dog was believed to have spent 15 hours in the sea water before he was pulled out and reunited with his owner.

When the owner saw this incredible incident he did not miss to catch on camera what one would only expect to see in the movies: a dog surfing on a dolphin. The dog hoped onto the animal’s back like it was no big deal and sits there for a few seconds. The dolphin must have noticed and allowed the dog to sit there anyway. Dolphins have been known to sometimes help stranded or injured people as well.
