Heartwarming footage has emerged of a tired five-year-old boy being surprised by his parents with his first dog.

The video, filmed in South Carolina, USA earlier this week, captures the amazing moment he was surprised with a ten-week-old puppy after asking for a dog for more than year.

And there's a nice backstory to the surprise too.

"Earlier that week he overheard my wife and I discussing the financial expenses of owning a dog and he ran full speed into his bedroom, returned almost as quick and without hesitation dumped out his entire piggy bank of litterally half his life savings on the living room floor," the boy's father wrote online.

This is a video of me surprising my five year old son w/ a 10 week old, amazingly cute 'teddy bear' puppy at the airport. Earlier that week he overheard my wife and I discussing the financial expenses of owning a dog and he ran full speed into his bedroom, returned almost as quick and without hesitation dumped out his entire piggy bank of litterally half his life savings on the living room floor. The great humor and 'awe factor of this video are partly to due to my son being very exhausted from the activities earlier that morning. He endured his basketball playoffs consisting of 2 games (the second he was tripped and injured/ bit his tongue ), then after 2 solid hours at Dave and Buster's arcade, ice cream, the first half of I am Legend (Will Smith zombie movie), then off to the airport where he had no idea what was in store. Take note to the position of his hands when my wife removes her cell phone from his hands. It's really funny because he's been asking for a dog for over a year, performing new chores around the house, doing awesome at school, and the time came, we finally ran out of excuses. He's such a good kid,. Well deserved.
