Actor David Duchovny has thrown his support behind a new spray and neuter program to help put an end to animal suffering.
The X-Files star shot an advert for the company 600Million.org, which aims to find a safe population-control solution so millions of dogs aren't abandoned or put down at birth.
In the video, the actor invites fans to follow his lead and help donate to the cause.
He says, "Please join me and 600Million.org in a unique project to help the number one cause of suffering for dogs -control the population. It's estimated that around the world there are over 600 million stray dogs, living in horrible conditions...
"Right now a team of scientists is working on a pill to sterilise dogs, which would drastically reduce the population - safely, humanely and cost-effectively - without surgery and without killing."
