A Laramie County Sheriff's K-9 proved himself to be the ultimate good boy last month when he sniffed out more than 250 pounds of marijuana.

According to a Facebook post, K-9 Tyr and his handler were called to a traffic stop on Interstate 80 near Cheyenne on April 28 after the Wyoming Highway Patrol requested a K-9.

"Tyr was deployed for an open-air sniff around the suspect vehicle (and) displayed a positive alert for the presence of illegal drugs inside the vehicle," the post reads.
