Soldier Reunites With His Military Dog Months After Injuries in Afghanistan Specialist Andrew Brown said his dog "definitely saved my life."

 -- Specialist Andrew Brown has reunited with his beloved military dog, Rocky, months after they were both injured in Afghanistan and received Purple Hearts.

Their reunion was caught on video Friday, three months after they were injured, separated and this photo of Rocky with his Purple Heart went viral.

Brown and Rocky had been partners for two years when they were searching a compound in Afghanistan in December and both were injured by shrapnel from an improvised explosive device (IED).

"When the explosion first happened, I was more worried about him than myself," Brown said.

After the explosion, they were flown together to Kandahar, Afghanistan, where Brown and Rocky were awarded Purple Hearts. Brown said flying together helped them both stay calm.

The two were then separated as Brown was flown to Walter Reed hospital in the U.S. and Rocky continued treatment in Europe.

Brown said being apart was difficult, but he knew Rocky "was in good hands."

Rocky is considered an American soldier, Brown explained to ABC News earlier, adding that a dog's rank is one above his handler's.

"He does everything," Brown said. "I'm just really a guy with a leash. I bring him to the area and let him do his thing. If he responds, I translate that ... let them know my dog got a response right here."

After undergoing treatment for his injuries, Rocky left Germany Thursday and began his trip back to the U.S.

Friday, Rocky finally reunited with Brown in Bethesda, Maryland.

Brown said this was the longest he and his dog had been apart.

"Just excitement -- it’s the only way I can describe it," Brown said of the reunion.

Brown, a father and husband, described Rocky as "a big part of me and a big part of my family."

"I’ve known him longer than both of my sons have been alive," he said. "I think we make a pretty good team --- you know, you've got to have 100 percent trust in your dog."

Since Afghanistan, Brown said he is doing well but doesn't "have a timeline of when I’ll be back to Fort Hood or be back to active duty. So I’m just taking it day by day and hopefully I’ll be back there soon."

Rocky is also doing well after suffering a broken femur in one of his hind legs and some injuries to his tail.

Brown said he'll adopt Rocky if the dog medically retires, but added that Rocky has "a high drive, so if he goes back to work I know he’ll do great things."

For now, Brown is looking forward to their first weekend together in three months -- their plan is "just spending time together, just like when we were in Afghanistan. He was with me the whole time."
