Which breed is the Italian water dog often cited as the ancestor of many poodles?

The story behind the answer

Lagotto Romagnolo is correct. This ancient Italian water retriever from the marshes of Romagna has a dense, curly, water‑resistant coat and strong retrieving instincts—traits mirrored in poodles. Because of this shared “water dog” toolkit and look, the Lagotto is often cited as a key ancestral type behind many poodles.

Interesting context: “Lagotto” derives from lago (lake), hinting at its waterwork roots, though the breed later became famous as a truffle hunter when wetlands were drained. While poodle origins are debated (Germany and France also claim influence), the Lagotto’s Italian heritage and curly, hypoallergenic coat make it an easy link. Memory tip: Lagotto → Lago → Lake → Italian water dog → early poodle.
