Ever wonder how to keep a police dog entertained for hours?

The Vacaville, California, Police Department posted a video to their Facebook page that shows exactly how!

The hilarious video shows K9 Roscoe having the time of his life with a red balloon.

And Roscoe deserves to have some fun. He and his handler were crowned "Best in the West" at a recent Western States Police Canine Association trial.

The competition tests police dogs in how well they can serve their departments in activities like sniffing out narcotics, search, agility, obedience and officer protection.

Way to go, Roscoe!

Watch the doggone entertaining video above.
