It’s not often that Riley, a K-9 unit member, is on base; when he is, however, you could always spot him hanging around Ghost and the rest of the task force (Soap has to visibly avoid the poor dog)..

Riley was as intelligent as its handlers and it was in no doubt that he could easily outdo majority of the operators. Though, he is equally as goofy when he is off duty as well.

At one point, you, Ghost, and Riley were hanging around the base; you and Ghost had some downtime together. Ghost had the idea of letting Riley loose for a moment, which he soon realised was a mistake when the dog senses his vest off and immediately takes off without warning…

“…that goddamn dog,” Ghost says as he stands there dumbfounded.
