The Hydro-Go, the newest in a line of products from the maker of Drinkwell The Original Pet Fountain , features a convenient fold out bowl which allows for easy drinking when you're away from home. And, its unique design allows for quick clean up. The bowl and canteen work together to form a funnel, easily allowing the unused water to be poured back into the canteen. This is truly a must-have product for road trips or outdoor adventures with Fido!
