In Lebanon County, the South Londonderry Township Police Department swore in its newest officer on Monday night.

K-9 officer Rex is a long-awaited addition to the department. His arrival is thanks to his handler, Officer Nick Ague, and many people who donated to raise a total of $40,000.

Ague saved a dog in a car crash last year, and the photo of that rescue went viral. Ague is an animal lover; because of the photo, donations came in from around the world to raise money to kept his department its first K-9.

Rex arrived in October from Europe. He's a 15-month-old German Shepherd who responds to commands in Czech. He and Ague completed four weeks of training together. Ague says they're already good partners.

"It's been a lifelong ambition of mine, so it's been one of the highlights of my life to actually start working with a K-9," says Ague.

A judge read Rex the police oath as he set his paw on the Bible, and then gave his pawprint in ink.
