With its tightly curled coat, otter-like tail, and whip-smart gaze, the Irish Water Spaniel is one of the most distinctive — and underappreciated — breeds ever to come out of Ireland. From its early mention in 1607 as the “Shannon Spaniel” to its refinement by the mysterious Justin McCarthy in the 1830s, this episode traces the story of a dog built for wetlands, made for work, and full of mischief. We follow its rise as a Victorian favourite, its influence on American breeds, and its quiet fight for survival today. A tale as deep and winding as the Shannon itself.
