Have you ever been in a situation where your dog is panting loudly and you overestimate just how thirsty it may be? Odds are, you have. In most cases, you want to overpour the water to ensure your best friend is well hydrated, and this often leads to you having to pour out any remaining water. No longer will that be an issue! Simply press the dispense button while holding the bottle upright and the water goes back into the bottle.
