The nutritional necessity of dogs is water. Adult dogs have about 60% water, while puppies have more water. The amount of water a dog drinks is an important indicator of its health. Too much or too little implies his health, so water is very important for dogs.
Because water is a necessary substance for metabolism, hormones and cell structures in the body must be involved in water to maintain normal state. Water is connected with the outside world through the body surface and respiratory system for heat exchange, which can lower the body temperature. If nutrients are insoluble in water, they cannot be completely absorbed. Especially for sick dogs, once they lack water, it is difficult to restore their original healthy posture.
Dogs can go without food for two days, but they can't go without water for a day. As long as the body lacks about 20% water, it will be life-threatening. Generally speaking, the daily water requirement of adult dogs is about 0/00 ml of water per kg body weight 150 ml of water per kg body weight/kloc-0. The owner must pay special attention to provide enough drinking water in high temperature or hot climate, or after exercise and when feeding dry feed food, and supply drinking water all day.
