They say a dog is a man's best friend. And while the canine's loyalty to its master remains unquestioned and time-tested, it's not just a one way street.
Take a look at this video that has come out of Yokneam, Israel for an instance. A man's dog had fallen into a mini ditch and despite his efforts he couldn't retrieve it out of the narrow opening. There came a local firefighting squad and helped the trapped dog out.
The joy of the man over being reunited with his dog was so immense that he started crying hysterically.
