Here's a breakdown:
Puppy Stage (Up to 18 Months):
* Physical Growth: Labradors reach their full size around 18 months.
* Mental Development: They are still learning and developing their personality, social skills, and obedience.
* Energy Levels: Labrador puppies have boundless energy, and they need a lot of exercise and mental stimulation.
Adulthood (18 Months and Beyond):
* Physical Maturity: Labs reach their full physical maturity at this stage.
* Mental Maturity: They are now more independent and mature, but their playful energy often remains.
* Energy Levels: Labradors still need a lot of exercise even as adults, but their energy levels may moderate slightly.
So, how long do they act like puppies?
While Labrador Retrievers reach physical maturity around 18 months, their playful and energetic nature can continue well into their adult years. You might find that your Labrador still enjoys chewing on toys, playing fetch, and cuddling up on the couch – even as they get older.
Key Factors Affecting Puppy-like Behavior:
* Genetics: Some Labradors are naturally more playful and energetic than others.
* Socialization and Training: A well-socialized and trained Labrador will be more likely to exhibit mature behaviors.
* Exercise and Mental Stimulation: Providing sufficient exercise and mental enrichment helps to channel their energy and keep them happy.
Remember: A Labrador's playful nature is part of what makes them such lovable companions. Enjoy their puppy-like energy, even as they mature into their adult years!
