Puppies go through several crucial development stages as they grow into adulthood. These stages are neonatal (0-2 weeks), transitional (2-4 weeks), socialization (3-12 weeks), juvenile (3-6 months), adolescence (6-18 months), and adulthood (1-3 years). During the neonatal stage, puppies are completely dependent on their mother for warmth, nutrition, and stimulation. The transitional stage marks the beginning of sensory development and interaction with littermates. Socialization is vital between 3-12 weeks, as puppies learn to interact with other dogs, animals, and humans. Juvenile stage involves increased independence and exploration. Adolescence can be challenging due to hormonal changes and testing boundaries. Finally, adulthood brings maturity and stability. Each stage requires specific care, training, and socialization to ensure a well-adjusted adult dog.
