Della will find water if there is any to be found. She is not above wallowing in a mud hole like a pig. There's no doubt that she's a Lab; she's true to the trait of being water loving. Some have speculated that Riley is part Labrador. Well if that's the case she did not inherit the water lovin' gene. She prefers to watch Della take a dip from dry ground, keeping her feet and everything else out of the water.
