Things You'll Need
- Electric heating pad
Instructions
Purchase an electric heating pad.
Place the heating pad below the water dish or bowl.
Plug the heating pad in.
Turn the heating pad on. If the heating pad has a setting, set it to medium as this should generate enough heat to keep the water in the bowl from freezing.
Keep the heating pad running all day so the water in the bowl never has a chance to freeze. Discontinue use of the heating pad when the weather is not below freezing. The heating pad will only warm the water and not make it hot.
