If your dog is like Kona and doesn't like to drink out of anything but a bowl, this is the perfect bowl for you. Around Tauranga there are people who know Kona for her collapsible bowl as it dangles on her back! Every time we are out in town or on a long walk, we just clip her bowl to her harness. It's lightweight and so easy to use and store. You can use it for food or water!
