Great pics! I had a kiddie pool for a dog (who is no longer with me) because she kept playing in the water bowl. I wasn't sure if she really used it but I did get pictures of her (which of course I can't find). She was so funny...was too hot in the summer but she practically knocked me off the bed in the winter trying to get close to me because she was cold.
All my mutts now think water is for drinking only which is fine with me because it makes the drive home from the dog park much cleaner and dryer!
And with you being in Austin you understand about the heat! Hope you are staying cool and your electric bill isn't killing you!
