Dizzy the Border Collie and her owner Natasha Wise, from Rickmansworth, have become the first pair to become three times world champions in dog agility.

Natasha, 30, and six-year-old Dizzy became the first ever dog and handler to win the prestigious FCI World Agility Championship on three separate occasions - 2009, 2010 and 2012 - after scooping another first place in the individual competition for medium sized dogs in the Czech Republic.

Natasha said: "I can’t believe we’ve managed to achieve the world champion title for the third time at the most prestigious international agility event. It really is an incredible feeling.

"Words can’t describe how amazing Dizzy is."

Natasha has been involved in agility competitions since the age of seven. She walks Dizzy daily as well as carrying out agility training once a week, which includes working with a canine physiotherapist, Maria Johnston.

The pair train at North Downs Dog Training Club and are members of Thames Dog Training Club, both of which are Kennel Club registered clubs. Natasha also teaches agility at Diamond Dogz Agility in her spare time.

She said: "Dizzy is very much part of the family. Her dad is my sister’s dog and I’ve had her since she was six weeks old.

"At home Dizzy is so relaxed - she is always lying on the sofa but as soon as I say ‘jumping’, which means agility training, she gets so excited and starts jumping around."

When it comes to training Natasha added: "I treat her like an athlete - we carry out specific equipment drills once a week to ensure she is in perfect condition."

Natasha and Dizzy also won the Championship Agility Medium award at Crufts 2012 and are three times winners of the Kennel Club Olympia Agility Stakes for the medium stakes category, and are competing again in this year’s finals to be held in December.

Natasha said: "Winning the Championship at Crufts and now the World Championships for the third time is incredible and to just qualify for Olympia is amazing. We aim to have a lot of fun as the event is so exciting in front of the Christmas crowd."

Natasha lives with her boyfriend Matthew and their six dogs.

Caroline Kisko, Kennel Club Secretary, said: "Natasha and Dizzy are superb athletes and two of the country’s leading agility stars. We hope their success will inspire other people to consider taking up agility as a sport, which is great fun for both dog and owner."
