"I had a few buddies that were prior service and had gotten dogs from Jeff, and they met Six and they just didn't quite mesh," Grassie said. "Then when I got there, he handed me the lead for Six and I was just like, 'Man this dog is really calm.' But when we went out and we did all the work and obstacle courses together, we just clicked."
Grassie said Greene had seen many dogs during his time as a counter sniper and member of special forces that were battle hardened and unable to integrate into home life, so he set out to train dogs to offer elite protection and still be good with families.
"We did the protection work, she bonded with me really well in like three days," Grassie said. "When we did a pretend assault, I was able to send her. She went with authority like she was going to take that guy that guy's arm off.
"She's very calm, she's very good with everybody, everybody can pet her. Like if she senses the intent of the individual coming toward me or anything that might be hostile, she recognizes that and completely just changes."
