THIS dog proved to be man's best friend when spotted on the back of a motorcyclist.

The bizarre moment of the dog hitching a ride on its owner's back was captured at Pontamman, Ammanford over the weekend.

It shows the goggle-wearing dog strapped to the back of the rider as they headed off on a ride.

The snap was taken by passer-by Kevin Hire while out walking with his wife.

He said: "Just when you think you’ve seen everything.

"Here’s something I’ve certainly never seen before, how to take your dog for a spin on your motorbike.

"It put a big smile on our faces."

Kevin added that the dog looked to be "loving it".
