A dog which was almost put down for being "too energetic" is now putting his life on the line for humans in the aftermath of Hurricane Harvey.

Rocket has been trained to save lives by the National Disaster Search Dog Foundation and is now assisting search and rescue teams with their recovery efforts.

His high energy - which almost cost him his life - has become his greatest asset.

The black and white border collie mix was rescued from an animal shelter where he was due to be put down because it was felt no one would want to adopt him.

However, the National Disaster Search Dog Foundation felt differently and decided to test him.
