A cool video has emerged of a buffalo running next to two seven-year-old boys in Wyoming, USA.

The footage, shot on May 4, shows Seth and Jackson calling the buffalo's name to make it run along with them.

"Once they started running in either direction he would follow and run along," Seth's mother wrote online.

"This went on for quite some time and it was fascinating to see him playing with the boys," she added.

7 year old best friends Seth and Jackson from Wyoming, USA went to the State Park with their mothers for an evening to see the new baby calf buffalo's. Instead King, the head of the heard was close to the fence and once the boys started walking, he would follow. Once they started running in either direction he would follow and run along. This went on for quite some time and it was fascinating to see him playing with the boys. It was quite the sight and they loved every minute of it!!!
