Baxter the spaniel would have lots of stories about his adventures if dogs could talk.
He has been reunited with his Queensland owners after going missing for seven years.
Penrith Council animal services found Baxter in Queen Street, St Marys, three weeks ago.
His microchip revealed he was registered to owners living on the Sunshine Coast.
"When we called them, they were overjoyed," mayor Mark Davies said.
"Within two hours Baxter was booked on a plane home to be reunited with his family the next day."
Penrith is one of the best councils in NSW for re-homing lost and abandoned dogs.
Of all dogs impounded at the Hawkesbury Animal Shelter from our area, 92 per cent are returned to their owners, sold to new owners or rescued by appropriate organisations.
Rangers and animal services staff make every effort to identify the owner of any dog found wandering, and impounding is always the last resort.
Owners can improve their pet's chances of being returned home safely by making sure they are microchipped and their contact details are up to date on the Companion Animals Register through any local council in NSW.
When selling or giving away a dog or cat, it's the current owner's responsibility to update the register with the new owner's details.
Penrith Council will hold a free microchipping day on September 21 at Jamison Park.
