A thick, muscular frame, webbed paws, and long, heavy coats make Newfoundlands adept at swimming in cold waters like those of the Canadian coastline.
The breed excels at long-distance swimming, as one of their primary roles as a working dog in Newfoundland was to haul in fishermen nets, carry boat lines to shore, and retrieve anything that fell overboard (including people).
And rather than doing the common “doggie paddle,” its swimming style is more like a breaststroke.
