Ozzy, a border collie/kelpie crossbreed, has entered the world famous tome for achieving the Fastest Crossing of a Tightrope by a Dog.
The four-year-old from North Wales, crossed a 3.5m rope in 18.22 seconds during his record breaking stunt at the Faith Animal Rescue Centre in Norfolk.
Ozzy now lives in Norwich with his owner, 51-year-old carpenter Nick Johnson, who has no formal dog training experience but learned the techniques from the internet. Mr Johnson said:
"Ozzy is most happy when he's working on the tricks that we do and regards it as a game.
It makes me feel so happy and proud, that Ozzy and I have such a strong friendship and relationship we can work together on tricks and games that get the recognition of Guinness World Records."
