This is a water dispenser specially designed for small and medium-sized dogs. At present, the water dispensers on the market are all small-capacity water dispensers, which are only suitable for cats. For this reason, a 7L large-capacity dog water dispenser with large drinking surface is specially designed. The water outlet is designed with three water streams that can easily wash away the dirt on the drinking surface, so that dogs can drink healthy and clean water all the time.
