Ash Barky stole our hearts as a puppy on Muster Dogs, and now Queensland's famous working dog is tackling a new job. The adorable border collie, who appeared with North Burnett grazier Cilla Pershouse in season two of the hit TV series, has become a mum, welcoming two male puppies last week. Ash — named after fellow Queensland icon, tennis champion Ash Barty — and Cilla appeared on Muster Dogs earlier this year, a program that follows puppies as they learn what it takes to become working dogs.
