Puppy growth is a rapid process that occurs during the first year of a dog's life. In this period, puppies typically double their weight in the first week and continue to grow quickly, reaching about 50% of their adult size by six months. Proper nutrition and regular veterinary check-ups are essential to ensure healthy development. During this growth phase, puppies also experience significant changes in behavior and socialization. They begin to explore their environment, learn basic commands, and interact with other animals and people. This is a crucial time for training and establishing good habits that will last into adulthood.
