Police who responded to a 999 call from a heavy breather were surprised to find the culprit was actually a dog.
Officers raced to the address of Mary Amos-Cole’s Buckinghamshire home, fearing the pensioner was in trouble.
It was hence with some relief they identified the panter was Leighton the dog and not the 76-year-old.
The two year-old Belgian Malinois had picked up the handset from a garden bench as his owner tended her plants and pressed the number 9 button three times with his teeth.
Amos-Cole said: "Next thing I knew there was a policewoman from Thames Valley Police at the door asking if I was alright.
"She said a colleague answered the call and all he could hear was heavy breathing. That's when we realised it must have been Leighton panting.
"They didn't know what our emergency was or which emergency service we needed, so she was sent to check our address.
"He's a very naughty dog but luckily we all took it as a bit of a joke."
Belgian Malinois dogs are commonly used as guard and search dogs.
Leighton has previous form with the police after setting off burglar alarms with his incessant barking.
Amos-Cole, a grandmother-of-five, added: "He does seem to quite like the police. He's been in trouble a few times and seems to quite like them coming round. I actually think he has aspirations to be in uniform himself."
Thames Valley Police said a "silent 999 call" was received from the address last Thursday afternoon.
A spokesman said: "At 12:57 it was confirmed by the occupant at the address that their dog had accidentally called 999."
The incident is reminiscent of the time a cat named Bruce Lee summoned officers to his owner's north London flat in a similar manner.
But the Singapura kitten didn't do any heavy breathing - instead opting to promptly hang up and hide in the wardrobe as confused police combed the otherwise empty flat.
