My dog will not drink from his bowl unless he sees me dump out yesterday’s water in the morning and fill it up with fridge water. My mom keeps a bowl for the dogs at her house, and the other day she filled it with tap water. One dog drank it, Snobface McGee did not. When my mom dumped it and refilled it with fridge water he drank it. He’s my buddy though so I will always make sure he has fresh fridge water.
