K9 members of the police force do so much for humans in the name of the law. They serve, protect, guide, apprehend, sniff, and give all– until their final breath. When Argo the German Shepherd joined the Hildalgo County Sheriff’s office, little did everyone know the huge impact his life would make on the team.

Thanks to K9 Argo, thousands of pounds of drugs were off the streets of Texas. He served as a Narcotics Detection Dog, partnered with LT Francisco Guerrero.

After many years of service, Argo was diagnosed with bone cancer, a devastating and progressive disease. Not one to let anything slow him down, Argo continued until the pain could no longer be tolerated.

In that moment, his partner made the most difficult decision a pet parent can make. A small, private ceremony would be held for loved ones to say goodbye to K9 Argo.

For his final minutes, Argo was given a fond farewell over the police radio. It is customary to say goodbye and wish an officer well, and this tradition was carried out for Argo. He lifted his head and his ears perked up when he heard his name.

Not a dry eye could be seen, as you will see in the emotional goodbye and gratitude video below. We salute you and thank you, K9 Argo.
