... and no, it wasn't Oscar waking us all up at 5.30am because a leaf fell off a tree. The winning dog was a German Shepherd called Daz, pictured above.Dogs from across the capital, with their owners in tow, went walkies into the Guinness Book of World Records yesterday (Monday) when they broke the record for the loudest bark in history.From pedigree pooches to mixed bred mutts, dogs of all shapes and sizes converged on Finsbury Park to follow in the pawprints of fictional superdog Bolt – the new Disney hero whose comedy adventure launched on Blu-ray and DVD yesterday.And far from making a dog’s dinner of taking the title from the current American holders, the Brits’ collective bark rose to 115 decibels, four decibels louder than the existing record set in Vermont, USA, last year.Top dog at Guinness World Records Marco Frigatti was on hand to oversee the record attempt and declared the attempt a success.He said: “Dogs bark for a variety of reasons, to attract attention or to express excitement. Today they barked to become Guinness World Record holders – congratulations!”German Shepherd ‘Daz Lightning’ also broke the world record for the loudest ever individual bark with a woof of 108 decibels.Bolt’s super bark is especially impressive on the high-definition Blu-ray disc which not only delivers five times the picture quality of DVD but also unbelievable sound.Academy Award nominated BOLT (2008, Best Animated Feature Film) is the first Disney feature to be conceived and produced under the guidance of Oscar®-winning director John Lasseter - the studio’s Chief Creative Officer and the brains behind Toy Story, A Bug’s Life and Cars.Voiced by two times Academy Award nominee John Travolta, Bolt is the star of the biggest show in Hollywood. The only problem is, he thinks the whole thing is real. When the super dog is accidentally shipped to New York City and separated from Penny - voiced by Miley Cyrus - his beloved co-star and owner, Bolt springs into action to find his way home.Together with his hilarious new sidekicks Rhino – Bolt’s #1 Fan – and a street-smart cat named Mittens, Bolt sets off on an amazing journey where he discovers he doesn’t need super powers to be a hero.Don’t miss Bolt’s great adventure on Disney Blu-ray and DVD now.
