29 Things You Didn't Know About Labrador Retrievers, America's Most Popular Dog

5. They Love Water
Because of their background, Labradors naturally love the water. While some dogs might shy away from a cold lake or a frigid sea, you will notice that Labradors often race in without any qualms. And one big reason for that is their double coat, which insulates them from the cold. The outer layer is waterproof which allows the water to bead right off of it, and the undercoat is thick and dense, protecting them from the nippy temps. This makes it safe for them to swim in freezing temperatures.
