After 10 years of service, Thunder Bay Police dog "Thunder" has retired.

Thunder leaves the force with a 70 per cent success rate for locating evidence, suspects and missing people.

It’s a remarkable number, as the provincial average sits around 30 per cent, said Constable Joe Prevett, who has been Thunder's partner for the past decade.

"He's earned his retirement,” Prevett said Wednesday at a goodbye ceremony at Thunder Bay police headquarters. “He's one of the busier dogs in the province and one of the most successful."

During his polcing career, Thunder has had to live outside.

Now that he's leaving the force, Prevett said there's a place for his partner inside his house — on the couch.

“During their work service they're outside all the time,” he said. “[But now] he'll have a spot in the house."

Prevett trained Thunder right from the start, in August of 2005.

“He graduated in December of 2005, so he's been in service since then ... all of his life,” Prevett said.

"We're together every day 24/7 ... it's a lot of responsibility, a lot of commitment of my part, and my family's part, but he's been an absolutely excellent family member and police dog.”

Thunder’s typical day on the job included locating drugs and guns, apprehending suspects, finding evidence and searching for missing people.
