This man's dog was missing for two years. After that much time, a lot of people might start to lose hope that they will ever find their dog again but this man was lucky enough to receive a call that his dog was found.
The dog takes a minute to sniff his owner, but as soon as he realizes who it is he is so excited! People who think dogs aren't intelligent are obviously not paying attention! This dog remembers his owner even after he hadn't seen him for two whole years! That's incredible and so heart-warming!
