- EASY TO USE AND WON’T STAY - Our patented one-handed hydration system is easy to use: just squeeze the bottle and the specially designed valve releases water into the bowl. Release your pressure and the water returns to the virtually leak-free bottle. 2. DESIGNED FOR CONVENIENCE - The 20 ounce bottle fits easily into any standard car cup holder. It features an adjustable Velcro strap that can be attached to the wrist or attached to a backpack or belt for easy carrying. 3. Get fresh water from a reliable source - Providing your dog with fresh, clean water can help prevent health issues associated with drinking from public water bowls and puddles, which may harbor disease-causing bacteria, parasites, or unknown toxins. 4. Simply squeeze the bottle to pump the water into the water bowl. Your dog or cat can drink water. The excess water can then be sucked off again if necessary. Universal water bowls are round, making them ideal for dogs of all sizes.
