Only my GSD did this, I think maybe it was because of her thicker coat (other dogs at the time were a Doberman and Cocker Spaniel). Afraid I don't have a solution; I just kept topping up her water! The bowl was outside, on the grass, so no clean-up required!
Rooster78, my current pup does this too! Except she runs away without digging the water out of the plastic container, lol. This way she leaves a trail of water.
