Fox Nation’s ‘Hero Dogs’: Meet heroic K9 who lost leg while protecting US soldiers in Afghanistan

In Season 4 of Fox Nation’s “Hero Dogs,” one courageous canine put her life on the line to save and protect the lives of 15 American soldiers in Afghanistan.

On the battlefield, Layka bit down on a deceased enemy killed in action; moments later, however, the enemy "resurrected himself" and shot 4-6 times in the dark room, the pup's partner and soldier Julian told host Emily Compagno.

"I could hear her screaming in pain," Julian said. "I knew she had been shot just by the way she had sounded."

Layka’s heroic charge gave another soldier enough time to take out the enemy for good, but Julian's "badly wounded" canine partner was tragically shot 4 times.
