The Hydro-Go! is a pet canteen unlike any other. The special design features a fold-out funnel bowl that allows you to return unused water to the canteen. The bowl can also detach from the canteen creating both a water bowl and a food bowl. The Hydro-Go! features an extra wide nylon strap for comfort and durability. Whether you are hiking, biking, camping, in the car or RV, the Hydro-Go! makes keeping your pet hydrated a breeze.
