The female dog, named Byrdie, got loose while being loaded onto Delta Flight 1573 to Memphis at 10:20 a.m.
The Rhodesian Ridgeback, approximately 30 pounds, ran around on runway 3L for about 10 minutes.
Passengers aboard the plane tweeted "dog on runway LaGuardia causes mayhem, passengers were not allowed to deplane"
Port Authority authorities quickly found the owner and brought her onto the runway to retrieve the runaway pup. The owner called to the dog, and the dog ran to her.
Two or three departing flights were briefly delayed.
Byrdie and her owner eventually made it to Memphis, safe and sound.
It's not the first time this has happened. A far less cute coyote alarmed pilots at Boston's Logan Field 2 years ago.
Last summer diamond back terrapin turtles en route to the beach to lay their eggs were in no hurry to cross the runway at JFK Airport as a Jet Blue pilot waited for clearance to take off.
