Doggy paddle: Part-Ex takes to the sea in coasteering

Part-Ex the Jack Russell has joined owner John-Paul Eatock, 30, on many adventures, earning him a unique distinction.

The six-year-old dog first ventured into the world of extreme sports at 18 months of age, climbing onto the back of John-Paul's surfboard as he headed out to sea.

From that point on, he has become known as a real action dog, taking part in kayaking, rock jumping, wind surfing and coasteering - the pasttime of following the coastline and jumping into the sea when the path runs out.

Now Part-Ex - named after a deal involving the sale of a horse box - is aiming for another extreme record by crossing the Irish Sea in a kayak with John-Paul.

His exploits have put him in the millennium edition of the Guinness Book of Records.

The pair have become celebrities in St David's, Pembrokeshire, and Part-Ex is set to get his own extreme website.

"I was surprised when he first joined me on the surfboard," said John-Paul.

"He does not like being left alone. If I do go out on big stuff, he does not have to go."

He added: "My friends and the local children really like Part-Ex. When it comes down to basics, he is quite happy curling up on the couch with me."

Part-Ex will be back in action again on 14 August, when he joins John-Paul in a two-man kayak from Rosslare in southern Ireland to White Sands, Pembrokeshire - a distance of 44-miles across the sea.

He will also be taking to the skies soon for his first parachute jump.
