The Lagotto Romagnolo is a medium-sized, curly-coated dog breed known for its keen sense of smell and affectionate nature. Originally bred in Italy for truffle hunting, it thrives in a variety of environments, including forests and rural areas. Its water-resistant coat and intelligence make it an excellent working dog and family companion.

The Lagotto Romagnolo is native to the Romagna sub-region of Italy, particularly in the marshlands of Comacchio and the plains of Ravenna.

The Lagotto Romagnolo originally thrived in the marshy and wet environments of Romagna, which were characterized by humid conditions and rich biodiversity. These areas provided a suitable environment for the breed's initial purpose of waterfowl retrieval.

Historically, the Lagotto Romagnolo's ecological niche involved being a water retriever in marshy landscapes. However, as the marshes were drained, the breed adapted to a new niche as a truffle hunter in the woodlands and rolling hills of the region. This adaptation showcases the breed's versatility and strong sense of smell, making it adept at finding truffles underground.
