Boot is bringing a whole new meaning to the term 'doggy paddle'. The Labrador can swim up to 4 kilometres at a time with his owners who are keen open water swimmers. He wears a special lifejacket to help keep him afloat and so he can be easily spotted in the water by passing boats. Open water swimming is one of the fastest growing sports in the UK and even though many dogs enjoy a quick dip, it's not thought many can match Boot's prowess in the water.
