Gus was on duty with his handler when he dropped and couldn't hold his head up.

Deputies rushed him to the vet where he died.

Authorities said a few days before that he cooled off in a pond after tracking down a suspect.

They hope Gus' autopsy will shed light on what happened.

The sheriff's office, Gainesville police and others paid respects to Gus Wednesday.
