It stands to reason that at some point in humanity's epic life-or-death struggle against the enormous, flesh-eating Titans, dogs are going to have to enter the fray. Cats don't give a single damn what happens to us, but dogs? They care, and will fight to the death to protect their givers of treats.
That's where these official Attack on Titan dog costumes come in, presumably. Whether they're tagging along with you to the next anime convention or simply guarding the walls of your home, now your furry little best friends can dress like a Survey Corps member. They arrive this fall in Japan (about $61 for the Survey Corps uniform, and $31 for the cloak).
However, you'll have to figure out for yourself how they're supposed to operate the 3D maneuver gear with their tiny little paws.
