Sorry, Rin Tin Tin. Your German shepherd features are no longer what the Transportation Security Administration is looking for in an airport screening dog.

Specifically, it's your ears. They're too pointy.

"We've made a conscious effort in TSA ... to use floppy ear dogs," TSA Administrator David Pekoske told the Washington Examiner during a recent tour of operations at Washington Dulles International Airport northern Virginia.

"We find the passenger acceptance of floppy ear dogs is just better. It presents just a little bit less of a concern," Pekoske said. "Doesn't scare children."

The Examiner reported that in the last year, 80 percent of dogs purchased by TSA from vendors were the following sporting, or hunting, breeds: Labrador retrievers, German short-haired pointers, wirehaired pointers, Vizslas and golden retrievers. All have droopy ears.

That doesn't mean TSA rejects all pointy-eared dogs. The agency does use the working breed German shepherd and the similar Belgian Malinois, both of which have cone-shaped ears. If a dog scores high on health, odor detection, socialization and disposition, it can still get a job.

But the dogs that screen passengers — one third of TSA's 1,200 canines — are more likely to have floppy ears, which are deemed less intimidating.

Jobs that require less interaction with the travelers, such as baggage bomb detection, can still fall to German shepherds, but the overall trend is definitely downward for the "police dog" breed at airports.

Breeders are increasing favoring "sporting" types of dogs rather than herders or other working canines.
