Written by HiromuArakawa in 1999, this one-chapter manga (published in a magazine at the time) was her very first serious work. It would eventually influence her later works, especially ''Manga/FullmetalAlchemist'', particularly in her own concept of alchemy itself ("chemistry and magic") as well as that of [[PettingZooPeople chimaeras]].

It focuses on the story of a bandit, Fultac, and his "military dog" Kilka. A "military dog" is a creature derived from the fusion of a human being and a dog (duh!), which is very loyal to his/her owner; originally used as soldiers, they are now pretty much pets, and the laboratory where they were created serves now as a factory. After finding Kilka, Fultac and her eventually face a bounty hunter mage and his own military dog; while said mage is killed, Fultac pretty much loses an arm, [[spoiler:and Kilka dies]]. Filled with anger he goes to the laboratory where he was created, facing the scientist/mage who is responsible for everything. [[spoiler:In the process we learn he was among his very first experiment, thrown away as a child to the sewers along with the carcasses of the other victims of the scientist/mage's experiments]]. After burning the place down Fultac kills the other military dogs to free them from their miserable lives, and ends up adopting a little military dog child himself,[[spoiler: who may or may not be free since he didn't performed the ritual of "bonding"]].

Overall a good TearJerker and heartwarming story, which is pretty much Fullmetal's prototype. Can be found [[http://www.mangafox.com/manga/stray_dog/ here, of course]].

!!This manga provides examples of:

* BittersweetEnding: More on the sweet side. The only reason why it isn't an happy ending is because [[spoiler: Kilka dies]].
* CrowningMomentOfHeartWarming: Fultac, and basically any interactions with [[spoiler:his second military dog. Perhaps even more admirable is the fact we don't see him doing the apparently necessary ritual to bond military dogs to their owners as he did to Kilka, so there's a chance that the child grew up to be a normal boy(?)]]
* EyepatchOfPower: Fultac. [[spoiler:Its hides a functioning, golden eye]].
* JerkWithAHeartOfGold: Fultac.
* LittleBitBeastly: young dogs look like this, while older ones are more {{furry|Fandom}}.
* LowFantasy: Despite the usage of science, magic is still used and the setting is medieval European looking.
* MadScientist: This coming from Hiromu Arakawa, it's really not surprising.
* MagicKnight: Fultac is a partial example: in addition to swordsmanship he knows exactly ''one'' spell, which is fairly powerful.
* LightIsNotGood: The bounty hunter mage uses light-based powers. Fultac later uses them, though...and it's still not good for the military dogs and for the mage/scientist.
* PapaWolf / BigBrotherInstinct: Fultac toward Kilka.
* ShoutOut: Fultac kinda looks like [[{{Berserk}} Guts/Gatts]].
* SupernaturalGoldEyes: That's how you distinguish a particularly human-like military dog from a normal person. [[spoiler:Fultac has one golden eye, indicating his status as one of the oldest military dogs.]]
