Hilarious Crufts video shows excited and ‘totally crazy’ Jack Russell failing at assault course – but loving every minute

AN excited Jack Russell left Channel 4 commentators in stitches after he went "totally crazy" during an agility course at this year's Crufts.

The terrier named Olly was filmed competing in the agility arena of the world famous dog show with his handler Karen on Sunday.

Hilarious footage shows the energetic pooch face-planting the floor after crashing through one of the barriers.

An announcer said while laughing : "Oh, what a nose dive! And he couldn’t care less."

The former rescue dog from Blue Cross shelter in Hertfordshire was captured jumping back onto his feet to continue the obstacle course with speed and stamina on side - but his precision wasn't up to scratch.

He refused to take any instruction from his handler Karen by ignoring other jumps and going through the tunnel the wrong way.

The announcer can be heard saying: "He's all over the place and so he should be. He’s going the wrong way, but it doesn’t really matter, does it?

"He is an absolute handful. (He is) totally crazy and as you can see he's having a ball. He loves life and exercise."

Summing up his performance, the announcer said: ";That’s one of the best shots I’ve seen in a long time.

"Well done the blue cross, persevere, first catch your dog."

Olly’s antics became one of the top trending videos on YouTube, earning him internet stardom even though he didn't get many points after his performance.

The clip on the video-sharing site has been viewed more than 800,000 times.

Crufts came to a close yesterday with an American Cocker Spaniel awarded the coveted Best in Show.

Miami Ink took out the top gong during the four-day event.
