Although I've had dogs that are supposedly "water dogs" such as Labradors and Leonbergers etc, none has really taken to the water. Of course, this is southern Spain so there isn't that much water anywhere, which hasn't helped.
Yesterday we took them to a river that we have just discovered that flows regularly throughout the summer. It's cool in the shade of the gorge, surrounded by high vegetation. here there is a small lake that's perfect for experimentation.
