Police Dog Dies in Line of Duty on Xmas Eve, Saves Cops' Lives

Terrible news out of Florida after a police dog was shot and killed by a suspect ... and the K9 is being credited for saving the lives of officers.

The sad incident went down on Xmas Eve in Wellington, Florida ... where Palm Beach County Sheriffs confronted several individuals cops say were wanted on attempted first-degree murder and armed robbery warrants.

According to local reports ... one of the suspects ran and that's when Cigo -- a 3-year-old canine -- gave chase. But the suspect shot Cigo before a deputy returned fire ... hitting the suspect and severely injuring him. Cigo, however, would later be pronounced dead at an animal hospital.

Shortly after Cigo's death, several tributes were posted in honor of the fallen officer. The Palm Beach County Sheriff's Office tweeted, "He gave his life to save others. He's a good boy and he will never be forgotten. Rest in Peace #K9Cigo."

The Sheriff's Office also posted this heartbreaking video of Cigo's handler devastated from the loss.
