NFL Legend Joe Thomas Attacked By Military Dogs In Wild Demonstration

Joe Thomas has gone from playing in front of the Dawg Pound to getting bitten by them -- the Cleveland Browns legend was viciously attacked by canines in a crazy demonstration at a military base!!

The 2023 Hall of Fame inductee and fellow ex-NFL star Whitney Mercilus hit up the Randolph Air Force Base in San Antonio in partnership with USAA ... where they got a full VIP meet and greet with the four-legged military sidekicks that are trained to locate explosives, narcotics, and personnel.

Thomas and Mercilus found out firsthand just how talented these doggos are ... 'cause they threw on some bite suits and agreed to run a 40-yard dash while being chased down by the animals.

Tech. Sergeant Hendrix warned Thomas and Mercilus before the demo ... "They are trained to bite and hold until we tell them to let go."

Despite the head's up, Thomas and Mercilus were ready to go against the dog with the strongest bite out of the bunch ... and let's just say they were doomed from the start.

The video is unreal -- Thomas barely made it a few strides before the dog launched into his back, clinging on for dear life before bringing the former offensive tackle to a complete stop.

"My heart rate was as high as I can remember, probably since I was playing football," Thomas said.

Both Thomas and Mercilus ended up being dragged to the ground by the military dog during the drill ... and thankfully, they made it out alive.
