Dogs are really man's best friend.
A loyalty you are sometimes trying hard to get from people around you is something you can surely get from a dog.
If you have watched the movie 'Hachiko', you can surely relate this video with it.
This dog had been waiting for her owner for 3 years and she just kept coming back on the same spot hoping to see her beloved human.
Warning: This can really be an emotional video especially if you're a dog lover.
