The oldest dog in the world, the 30-year-old Kelpie, Maggie died at a dairy farm in the state of Victoria in Australia. The Brian McLaren, a dairy farmer, confirmed the death of his dog. McLaren said that Maggie was active and was chasing away cats and was involved in all activities. Maggie came in as an eight-week old puppy thirty years back when his son was four years old. The national media made the dog a celebrity overnight after McLaren called it the oldest dog in the world. But sadly there are no ownership papers to prove the claim.
