Splash!

After Jonty has sprinted up and down chasing tennis balls for quarter of an hour he decides a pant is in order and plops into the dog pond with his ball for a drink and a pausette. Which is all very well but he never seems to have been taught how to shake. So he gets out of the pond and just drips during the walk until he dries off. We try to keep him out of the water before he gets back in the car. Is this a rescue dog thing do you think?
