They say a dog is a man's best friend, and for one Army veteran, truer words couldn't be spoken.
Retired Staff Sgt. Randall Dexter had been a witness to several harrowing ordeals during the course of his service. He served in Iraq twice, where in 2015 he saw his crew be hit with an improvised explosive device (IED).
Despite being a medic, Dexter was unable to save his fallen comrades, which led to his diagnosis of post-traumatic stress disorder (PTSD).
"Three Iraqi civilians were severely injured," Dexter said. "One of [them] had a mortal wound to his head."
Things wouldn't immediately improve for Dexter, as he suffered a traumatic head injury following a flag football game.
Dexter began taking 14 medications per day, which included sleep medications, antidepressants, migraine medications, anti-anxiety medications, and injections for a blood clot.
"It was brutal," he told TODAY. "I was contemplating suicide and was a hot mess."
"I was a walking zombie because the medications kept me physically drained and very hazy mentally," he also shared with The Epoch Times.
Thankfully, Dexter would never succumb to his suicidal thoughts after he was introduced to his new best friend.
