I'm not an expert by any means, by there definitely has to be a genetic or instinctual link to this game with the CSV. Splish, Splash, Kerplop!! Over and over and over...
Oh, keeping any water in the water bowl (for drinking) used to be such a challenge! I used to get so frustrated (as well as amused) that I ended up getting something like 10 different water bowls, hiding several in obscure places in the yard, and then only "showing" my non-CSV dog where they were so she could at least have some water to drink.
The plastic kiddie-pool did help some as well, regardless of whether it was summer or winter. Then I went through about 5 or 6 of those when my CSV discovered how fun it was to shred them apart.
Eventually the dunking and splashing wore off - at least in the drinking water bowl.
