The incident occurred on the 15th of September aboard Southwest Flight 4981, from St. Louis Lambert International Airport (STL) to Fort Lauderdale-Hollywood International Airport (FLL). According to a passenger onboard, the flight had been mostly uneventful until the end of the journey.
Incident occurred shortly before landing
A passenger reported that a Belgian Malinois seated in the bulkhead area of the plane became increasingly restless with around 25–30 minutes remaining in the flight. The dog was supposedly at its owner’s feet at seat 1C.
The animal subsequently had its unfortunate accident in the aisle at the front of the cabin. Because of the location of the incident, the incident was difficult for the crew to manage, as the area was directly on the pathway (the corridor) passengers would use to leave the aircraft.
Flight attendants attempted to clear the mess using paper towels while the aircraft continued to Fort Lauderdale. With limited time remaining before landing, a complete cleanup was not possible in the air.
The affected section was covered with paper towels, and passengers were warned to be cautious when leaving the aircraft.
Boeing 737 MAX 8 continued operating
Flight 4981 landed at Fort Lauderdale at around 1:40 p.m. local time. There were no reports that the incident affected the aircraft’s ability to complete the flight.
Flight-tracking information shows that the Boeing 737 MAX 8 involved, registered N8975K, subsequently departed Fort Lauderdale at approximately 2:59 p.m. for Baltimore/Washington International Airport (BWI).
The turnaround meant that ground personnel had to deal with the affected area before the aircraft returned to service.
Airlines have supplies that allow crews to contain biological contamination during a flight, while more extensive cabin cleaning is generally performed by ground personnel after arrival. The precise cleaning procedures used on this aircraft have not been publicly detailed.
Questions surrounding the dog’s status
The passenger described the dog as a service dog. However, the available information does not independently establish the animal’s service-dog status.
Southwest’s regular in-cabin pet policy applies to small cats and dogs traveling in an appropriate carrier beneath the seat. Service dogs are treated differently under US federal regulations and are permitted to accompany passengers with disabilities.
The US Department of Transportation defines a service animal for air travel as a dog trained to perform work or tasks for a person with a disability.
The passenger claims the dog wore a collar marked “Do Not Pet.”
Not the first airline incident involving a service dog
Service-animal incidents have previously created unusual situations aboard commercial aircraft.
In 2024, a United Airlines flight diverted after a service dog had an accident in the first-class cabin. More recently, Southwest was also involved in a separate incident concerning a passenger whose service dog was reportedly accused of defecating at an airport service desk.
The incident on Flight 4981 did not prevent the aircraft from reaching its destination. Instead, its primary issue was on the cabin environment and the deplaning process, leaving passengers with an unusual obstacle to navigate as they exited the aircraft.
