Bonus Chapter: Dog of the Military?

Sergeant Major Kain Fuery carries a rain-soaked Shiba Inu puppy into headquarters after rescuing it, but his dormitory bars animals, so he begins hunting for a willing owner among his colleagues. The candidates fall away one after another. Vato Falman lives under the same no-pets rule, Heymans Breda cannot conceal his terror of dogs, and Jean Havoc rules himself out with a tasteless quip about how tasty the animal would be stir-fried, which he later insists was only a joke. The constantly traveling Elric brothers cannot commit either, and when Edward scolds Fuery for adopting a creature he lacks the means to support, he immediately catches Alphonse smuggling a stray cat inside his own armor and orders him to put it back, sending a tearful Al running off with the cat still hidden.

Colonel Mustang seems like a possibility until he cheerfully praises dogs as uncomplaining, faithful servants, which disqualifies him too. Fuery finally admits to Riza Hawkeye that no home has turned up and reluctantly prepares to return the puppy outside. At that moment Hawkeye announces she will take the dog herself, thrilling the young soldier. The other officers gather to watch her feed her new pet, only to see her fire a burst of rounds at the animal the instant it relieves itself on a wall, an unnerving introduction to her notion of discipline. As she sets about housebreaking the frightened puppy, the equally rattled officers slip away, each silently vowing never to cross her.

A later comic short reveals that Hawkeye names the dog Black Hayate, a title meaning Black Hurricane that Mustang treats as proof of her questionable taste in pet names. The events depicted here were later worked into portions of the 2003 anime's thirteenth episode, Fullmetal vs. Flame. Fans have also flagged an art error: seven bullet marks are visible on the wall behind the puppy, even though Hawkeye is shown firing only six times.
