Sarco

A museum guardian. This elegant canine patrols the halls of museums or art galleries, sniffing out those with bad intentions. They rarely stay in one place for long as they follow a collection as it tours the world. They deeply enjoy travelling and meeting new people, though, unfortunately, dislike the smell of paint.

Sarco lives for his assignment; yes, he was genetically created for the job, but he truly lived for the artifacts and the arts with such rich histories.
Unfortunately, his borderline allergic reaction to prolonged paint smell exposure, put him in a predicament. This fault was compensated by allowing him to do frequent exterior patrols to clear his senses. It was during such, that the statuesque creature made a friend.
A scrawny man tending the register at the museum gift shop. The man stumbled over his words more often than not, but he clearly admired history. The sharp dog did not miss the devotion hidden within such an easily overlooked figure.
Sarco timed his exterior patrols with the man's breaks so that they could walk together. Once the man had gotten past his shock of the tracker dog tailing him, they formed a sort of mutual respect and understanding. Sarco was ever alert to his task as they walked, but he also cataloged every passionate word the man said about the stories behind certain exhibit pieces. It became routine for them to seek out one another's company.
When Sarcos' assigned exhibit was announced to move, he became noticeably agitated despite his usual love of travel. After eventually figuring out the source of Sarco's hesitation; the exhibit manager saw no other solution than to offer the stranger a position as Sarco's official handler.
The two have been inseparable since and not a single artifact has gone missing under their watch, so far.
