Do Corgs stay wet longer than other dogs, or is it just mine?

Title, obviously. I brought my 10 month old boy to the lake for his first swim today. It's been well over an hour and a half and he has done the shakes many times since the last time he was in the water.

​

But he's still wet. I'm assuming it must have something to so with their original intended purpose of herding in a wet and cold environment.

It's just odd. I don't recall every encountering a dog which stayed wet for so long.
