(Hydrahorse) Hydrahorse Complete Horse Waterer is a revolutionary system that can solve watering and dehydration issues and change the way you travel with your horses and livestock. With a one-of-a-kind, patented design, HydraHorse provides an in-trailer, mounted “drinking fountain” for your horse that supplies water on-demand during transportation. Made of durable aluminum specially designed for your horse’s safety and usability. The horse pushes against the nozzle and water automatically flows into the bowl. When the horse draws back, the flow of water immediately stops. The anodized bowl that holds the water for drinking has a curved lip that avoids spillage and avoids any sharp edges that could be hazardous to your horse.
