Water is the essential nutrient for dogs. Adult dogs have about 60% of their body water, while puppies have more. The amount of drinking water is an important indicator of the dog’s health, too much or too little indicates the dog’s health, so water is very important for the dog. Because water is necessary for metabolism, hormones and cell structure in the body must be involved in water to maintain normal condition. Water will alternate with the outside world through the body surface and respiratory system, which can reduce the body temperature. If the nutrients are not dissolved in the water, they cannot be fully absorbed. Especially for sick dogs, once they lack of water, it will be difficult to restore their original healthy body.
Dogs can not eat for two days, but can not drink water for one day. As long as the body lacks about 20% water, there will be a life crisis. In general, adult dogs need about 100 ml of water per kilogram of body weight per day, while puppies need about 150 ml of water per kilogram of body weight. The owner must pay special attention to providing enough drinking water in high temperature or hot climate, or after exercise and when feeding dry feed food, and providing drinking water all day.
