Mark Ingram learned on Wednesday just how ferocious a security dog can be.
The New Orleans Saints running back is spending the week in Europe as part of an NFL-USO tour to visit U.S. troops and their families at military bases in Italy and Germany.
And, apparently, the other players dared Ingram to try his luck against a guard dog at Aviano Air Base in Italy.
In a video from NFL.com's Marc Sessler, Ingram said he stood tall when the dog attacked the first two times, but the video most people will see on the internet Wednesday afternoon is of the dog snatching Ingram to the ground.
