Texas shelter dog becomes impressive police K-9 as he combats fentanyl crisis

Rock, a German shepherd mix, was found wondering the streets last summer. Now, in less than a year, he's become a top narcotics K-9 at the Fort Worth Police Department.

Rock, a long and dark-coated German shepherd mix, is part of narcotics detection operations that have taken hundreds of thousands of pills off the streets — making him a vital tool in combating today's fentanyl crisis. "We can't do this job without a K-9 like him. It’s the most effective way for us to combat fentanyl, heroin, meth, cocaine, all of it." "Three of our six K-9s are shelter rescues now." Gretchen Eichenberg is a contributing reporter for Fox News Digital.

"I'm talking 20,000, 100,000, 500,000 pills off the street before they ever get out into our community," Hubbard said of the role narcotics detection K-9s play in law enforcement.
