The 12 dogs vying for the title of the hardest working farm dog in Australiaand New Zealand have put in a tremendous effort in the first half of the 2021Cobber Challenge.

Victorian dog Skyblue Jack has clocked up 513.5 kilometres to put him in theoverall leader position by day 10 of the three-week competition.

The six-year-old Kelpie has worked 45 hours recording an average speed of11.41 km/hour.

Jack’s strong performance comes as a pleasant surprise for owner Ben Jeffery.

“Jack’s happiest when he’s working, but he’s stepped it up. I’ve never seenhim so happy and fit. He’s wagging his tail and running all day. He’s justworking so well for me.”

Jack spent two months before the Cobber Challenge slowly recovering from aninjury – he had to have a dewclaw removed after a fight with another dog. Benis thrilled his main dog was match fit for the competition.

“I couldn’t be prouder of him,” Ben says.

Ben and Jack work at Mepungah Pastoral in Wannon in Victoria’s WesternDistrict. Split over a few properties, the operation spans 3200 hectares andthey run 28,000 sheep and about 1000 head of cattle.

They have been working dawn to dusk most days – drenching sheep and checkingon other mobs that are lambing. They’ve also been rounding up a few cheekycattle that have gotten into the wrong paddocks.

In second place midway through the Cobber Challenge is fellow VictorianKelpie, Glenlyon Jill. She has recorded 347.82 km over a total time of 37hours, to achieve an average speed of 9.31 km/h.

Jill’s owner James Leahy says he’s enjoying seeing the data at the end of eachday: “It’s a good representation of my working dog.”

The Cobber Challenge is in its sixth year. Organiser Kellie Savage, Cobber’sMarketing Manager, says these dogs are on track to beat the record of 835 km,set by Glenda Rogan and her dog Buddy last year.

“The amount of work these dogs have done is incredible. And while these twoVictorian dogs are in the lead, there is still plenty of time for othercompetitors to make a late run,” Kellie says.

“Look at Koby from NSW and Pine from New Zealand, they are nipping at theirheels!”

It is the first time New Zealand dogs have competed, and the country isrepresented by three Heading Dogs. Pine from Ashburton on the South Island iscurrently ranked the highest, after helping owner Cam Clayton move sheep forpre-lamb shearing.

Owner Cam Clayton says the Cobber Challenge has helped him realise how muchPine actually works.

“I fully appreciate the dogs for their hard running efforts and ability to dothe job but the sheer distance they cover is just astonishing.”

In the second half of the competition, Cam and Pine will be sorting cattle forpre-calving and getting the ewes set for lambing.

In true sporting behaviour, an injured ankle is holding back fellow Kiwicompetitor, Josh Tosh from working his normal hours with dog Trix. But he’sdoing all he can to get Trix out in the paddocks and submitting her GPS data.

The 12 competing dogs are wearing a GPS collar to record the distance,duration and average speed worked. The Cobber Challenge runs for three weeksand this year will finish on Sunday 5th September, with the Cobber Championannounced the following day.

Kellie says the impressive work done by all competitors highlights theimportance of working dogs to agriculture across Australia and New Zealand.

Cobber Working Dog Food provides the fuel for the dogs competing in the CobberChallenge as well as thousands of others working hard every day around thecountry.

Data is uploaded each day. People can follow the performance of theirfavourite dog at and on the Cobber DogFacebook page.
