The world record for the highest jump cleared by a dog is 172.7 cm (68 in), achieved by Cinderella May a Holly Grey, owned by Kate Long and Kathleen Conroy (both USA) of Miami, Florida, USA, at the Purina Incredible Dog Challenge National Finals, Gray Summit, Missouri, USA on 7 October 2006.
The longest rabbit ears measured 79 cm (31.125 in) in a complete span on November 1, 2003 at the American Rabbit Breeders Association National Show in Wichita, Kansas, USA.
The dog-called Mr. Jeffries, had ears measured at 29.2cm in November 2002.
His grandad used to hold the record, but when he died Mr Jeffries took over.
His ears are so valuable that his owner has insured them against damage for £30,000.
Owner Phil Jeffries says the ears are so long that he often stands on them, trips over them or drags them in his food by accident.
A colossal shire horse in Australia has been proclaimed the biggest horse in the world by its owner, beating the current Guinness World Record by several inches.
The giant five-year-old, from Pakenham, S.E Australia, measures a staggering 20.1 hands, or 2.057m tall. He weighs over 1.3 tonnes (1300kg) - about the same as a small car - and is still growing.
His owner, horse trainer Jane Greenman, 47, says the only time the lumbering beast runs is when there is food on offer.
