Missing dog found after almost two years 300km away from Australian home

An Australian man is over the moon after learning his dog, who was lost for almost two years, has finally been found alive and well.

Jake Hennessy was left devastated days after Christmas in 2017 when his home in Kalgoorlie, Western Australia, was broken into and his puppy missing.

He instigated a search for the mastiff cross shar-pei named Harley, posting to a local lost and found pet Facebook group to “please help return my baby to me”.

Nineteen months later, Harley was spotted roaming the streets and scavenging food at Leonora - more than 280km from where he went missing.

Remarkably, it would have taken a car three hours to drive the distance.

A volunteer picked Harley up and bought him to Kalgoorlie so the lost pet could get checked over by a vet, Abby Kumar Buccilli from Kalgoorlie Dog Adoptions told the ABC.

"We all remember when he went missing a year-and-a-half ago and who would have imagined this stray dog was Harley," she said.

Mr Hennessy, who has since moved to Brisbane, is expected to be reunited with his mate as soon as Harley is well enough to make the trip.

"I feel like I've won lotto, I was going to buy a ticket tonight but now I don't need to," he told the ABC on Thursday.

The good news has warmed the hearts of pet lovers across states.
