Oktane, the beloved K-9 officer of the South Euclid Police Department, died on Wednesday after being diagnosed with cancer.

In a Facebook post written by Oktane's handler, Officer Dustin Smoot, the K-9 had begun to lose control of his bodily functions and the jaundice that had affected him had become worse.

"Upon consulting with the oncologist and learning of what lay ahead for Oktane, I made the difficult decision to allow him to pass with the dignity that he deserves," Smoot wrote.

On Tuesday, Smoot announced that Oktane had been diagnosed with cancer and would be retiring from duty with the South Euclid Police Department. Oktane's prognosis had been 6-12 months.

Smoot closed his Facebook post with this heartbreaking tribute: "Please watch over heaven and be sure to meet up with Rex and Recon, pal. I love you very much and will forever cherish your unwavering devotion and love to me."
