I think it's instinctual. Webbed feet = Water Dog. Even a mutt with webbed feet will take to water without giving it a second thought. If they don't have webbed feet then some like it, some don't. People who own swimming pools and don't want a dog that is always going in the pool (i.e., stinky wet dog) stay away from dogs with webbed feet.
Very true words. I've always taken my dogs swimming no matter the breed. Right now we have a Yellow Lab and she loves to stand out in a downpour trying to catch rain drops in her mouth.... it cracks me up watching her. It's not so funny when all 80 pounds of her wants to come back in though....
