Why isn't the water hot? Can I adjust the temperature?

The temperature is set at our water heater, and re-circulated to the tubs by an electric pump, to keep it at a constant level. Because dogs tend to overheat when they are nervous (is Fido panting?), the lukewarm water may seem a bit cool to you, but it will be more comfortable for your dog. As all four tubs are on the same system, the water temperature cannot be adjusted individually. Using this automated temperature system is safer, as it prevents owners from inadvertently burning their dogs (or themselves), with water that is too hot. Generally speaking, we keep the water temperature a bit higher in winter, and cooler during warm weather months.
