"Has anyone wondered what this means on our K9 vehicles? If the horn is beeping it means our heat alarm is going off," the Albany County Sheriff K9 wrote on Facebook.

When the car is parked and the horn goes off, this means a police K9 is in the car that is overheating. The car's windows roll down, but the dog is still in danger.

"Attention! Horn beeping dial 911," a sign on an Albany County Sheriff's Office patrol car reads.

Police say if you hear the horn beeping you should call 911 right away. This could save the K9's life.

"Sometimes our officers have to leave their K9’s in the car to handle a call," the Albany County Sheriff K9 adds. "Even with climate settings mechanical failures can still happen. If you hear the alarm, call 911. This could save our partners life!"

Try and remember this tip if you ever do come across a parked police car with its horn beeping because you could save a beloved dog's life!
