(Tampa Fire & Rescue/ Twitter) The two-year-old golden retriever is now the proud mum of eight puppies.
Mother Nature's timing can be a bit unpredictable.
Van Atter said people from all over came over to help, and thankfully she had packed towels just in case.
A service dog delivered a healthy litter of puppies at Tampa International Airport, Florida, after going into labor as she waited to board a Philadelphia-bound flight with her owner.
"The unusual scene drew quite a crowd outside of the Gasparilla Bar at TIA's Airside F. Officers, airport employees, and passengers all paused to watch the pups" arrival.
Paramedics were at the airport and assisted with the delivery.
"It's a girl!" Tampa Fire Rescue announced on Twitter.
"It's absolutely something I will never forget and the airport will never forget", Van Atter added.
Ellie, who was pregnant with 8 puppies, gave birth one-by-one with the puppies' dad, Nugget, also Van Atter's dog, right by her side. They are waiting for two more puppies.
Van Atter says she will be donating one of the puppies to a children's service dog charity.
