After what’s been some tough times for him recently, Fort Collins Police Services’ K9 Yago is back on the beat.

He returned to work on March 19 and is doing well with his health, said Fort Collins Police Services spokeswoman Kate Kimble. He’s done a number of drug sniffs and a building search.

It’s amazing that K9 Yago is alive to come back to work at all. After K9 Yago underwent successful surgery to remove a benign tumor from his hip, police say he suffered a mesenteric torsion, which is where the intestines spontaneously flip or twist.

About 90 percent of dogs die during the emergency surgery he was rushed into to correct that. But K9 Yago, clearly, is tougher than about 90 percent of dogs.

He is underweight because of the surgery, Kimble said, but police are working to build him back up to what he was.

It’s actually for the best that K9 Yago has returned to work so quickly, as he gets more anxious when he’s not working than when he is, she said.

“He and all the K9s just love working,” she said.
