Spleash Your Leash®. Walking your dog is now more comfortable and less stressful. Attach Spleash® your favorite leash, and you can quickly refresh your pet with a squeeze of your finger without having to grab or carry anything other than your leash. Spleash® holds up to 12 oz of fresh drinking water. Spleash® also provides a great defense against off-leash animals approaching, with a 14-foot spray distance, spraying Spleash® allows for some defensible space between you and the off-leash animal.
