Crying and speechless, an Auckland dog owner couldn't believe her luck when she was reunited with her beloved Siberian Husky, five months after it went missing.

Titan is reunited with his rightful owners

Nine-month-old Titan disappeared without a trace on January 5. His owner Lavinia Moala, 21, found the gate open but failed to find the pup anywhere and suspected foul play.

Despite Ms Moala "never giving up hope" of a reunion and posting photos of the dog online, the odds of Titan returning grew increasingly slim.

Then, after five months, an Auckland Council animal control officer found the pedigree dog with another person, who was "certainly not the legal owner" and refused to give their details.

Titan was impounded at the Manukau Animal Shelter yesterday and with the help of micro-chipping technology he was reunited with his rightful owner.

"As soon as we contacted the owner they came in extremely excited to get their dog Titan," Auckland Council Animal Management manager Tracey Moore said.

"This family were reunited with their dog after all this time because it was micro-chipped. Registering and micro-chipping dogs is essential so we can return dogs to their owners in such circumstances or even when they just wander off a property."

Ms Moala said after being reunited with Titan today: "I was crying, speechless. I take him everywhere with me, I am just so lucky to get him back."
