Dogs that are one month old can drink water. In fact, water is very important for dogs. They need enough water to maintain the normal functioning of their bodies. Water is especially important as your dog grows, as it helps your dog maintain a normal body temperature, digest nutrients, maintain healthy skin and coat, and eliminate waste from the body.
When dogs are just born, they usually get enough from the mother’s milk of water and nutrients, but when the dog begins to gradually wean and starts eating solid food, it will need to gradually start drinking water. Therefore, even a one-month-old dog needs enough water to stay healthy.
