The pure bred black-and-tan kelpie is one of two Tasmanian entrants, along with fellow kelpie Flow of Fingal, competing to be the top dog in the 2017 Cobber Challenge.

The challenge started on Monday and will run for three weeks, with 12 entrants from around the country vying for the title of Australia’s hardest working dog.

Angel’s owner Alexander Gregory said the three-and-a-half year old was a natural with the sheep and cattle on his 12,400-hectare property.

“I’m interested to see how far she goes and how hard she works. It’s lambing time now so she’s been checking on the ewes and lambs,” Mr Gregory said.

“Angel is loyal and never gives up. I bred her from a pup and she’s been coming out with me every few days right from then. She always wants to be with me,” he said.

Angel clocked up nine kilometres in two hours when helping out with drenching last weekend, Mr Gregory said.

Flow’s owner Bradley McDonald said he was also interested to see how the Fingal kelpie fared in the competition.

“Tasmania didn’t have any dogs in last year’s competition. I’m interested to see how the data from Flow compares to other states,” Mr McDonald said.

The 2016 winner, Larry from Victoria, set a big total to beat, covering more than 50 kilometres per day.

Data from the 12 tracking collars is uploaded daily until the Cobber Challenge finishes on September 17.
