When I think of water bottles, I think of something like this: (but not as fancy)
Amazon.com: PetSafe Healthy Pet Water Station,...
I have a Drinkwell Pet Fountain right now (
Amazon.com: Drinkwell Platinum Pet Fountain... ). But that doesn't stop her.
I actually DO have a kiddie swimming pool. And I was going to pull it out of my garage this morning, but it was a little chilly. So now I'm definitely going to pull it out this afternoon.
Hopefully she'll get her fill of digging water from the pool. We'll see...
