Maned wolves are the largest canids of South America, known for their distinctive long legs and solitary lifestyle. Zoo welfare depends on understanding their unique social structure, diet, and territory needs.
Maned wolf welfare in captivity requires specialised nutrition above all else. Standard carnivore diets cause cystinuria — a metabolic disorder leading to bladder and kidney stones — because the species has unique amino acid metabolism. Fruit, particularly the lobeira (wolf apple), must be included in the diet along with appropriately formulated protein sources low in cysteine and methionine. AZA and EAZA nutrition specialists have developed maned wolf-specific diet protocols that dramatically reduce stone formation. Socially, maned wolves should be housed in mated pairs with the ability to separate as they would in the wild — forced cohabitation causes stress. Large enclosures with tall grass areas, varied terrain, and enrichment that engages their omnivorous foraging (hidden fruits, buried invertebrates) support behavioural welfare. Frequent veterinary monitoring for bladder stone formation is essential as a welfare safeguard.
