Sam Merlotte, a shapeshifter, is the owner of the bar/restaurant Merlotte's Bar and Grill in Bon Temps, Louisiana. In his early 30's, he is of average height and strong build, with gray eyes and shaggy brown hair, much in line with his alternate form. While he can change into any animal (so long as there is a suitable 'template' animal around for him to use as a basis), Sam's preferred alternate shape is that of a light-colored border collie.
Like all shapeshifters, Sam feels a strong urge to change shape on the nights of a full moon. The rest of the time he can do so at will. He often will go for runs in dog form through the local woods with his canine friend.
