PUPDATE:

Harley AKA Sully & Loki are clearly water dogs.   They seem to be on rotation taking turns on who gets to sleep in the full water dish.   And this water dish is huge.  It is a sight to see.  The dogs are frequently completely crashed with half their body submerged.

Miss Cali, she thinks she can swim through the water dish, paddling her way through the water bowl.  Although clearly she can touch the bottom, it is much more fun to do the dog paddle.   It is a riot!
