The maned wolf is omnivorous. It eats armadillos, rabbits, rodents and other small mammals, fish, birds, bird eggs, reptiles, gastropods and other terrestrial mollusks, insects, seasonably available fruits, and other vegetation. Fruits taken include bananas, guavas, and primarily the tomato-like Solanum lycocarpum. (S. lycocarpum may provide medicinal aid against Dioctophyme renale, a worm that infects the kidneys of the maned wolf). Vegetation eaten is often in the form of roots and bulbs. Vertebrate prey do not often include large domestic stock, but an occasional newborn lamb or pig is taken by Chrysocyon. The maned wolf, much to the dislike of poultry farmers, frequently feeds upon free-ranging chickens. It stalks and pounces in a fox-like manner upon its animal prey.
