The ideal age for a puppy to leave its mother is between 8 to 12 weeks old. During this critical period, puppies learn essential social skills and behaviors from their mother and littermates, including bite inhibition, social cues, and proper interactions with other dogs. By 8 weeks, they are typically weaned and can start adapting to their new homes. However, staying with their mother and siblings until 12 weeks can further enhance their socialization and development. Puppies leaving too early, before 8 weeks, may face behavioral issues later on, such as anxiety or aggression, due to a lack of these vital early experiences.
