Are dogs born knowing how to swim?

Not all dogs are born swimmers; only some breeds have a natural talent, such as Labradors, which usually learn fast. Short-legged breeds like Corgis, Bulldogs, and Dachshunds mostly find swimming very hard because of their build, and even professional training rarely makes them proficient.

Still, some dogs that are not natural swimmers become strong swimmers after proper professional training — herding breeds, for example.
