Until approximately what age does the sensitive period last in dogs?

The sensitive period in dogs primarily lasts until about fourteen weeks of age. During this time, puppies are particularly receptive to socialization and learning. This period is crucial as it lays the foundation for a dog’s behavior and personality throughout its life. Engaging with various stimuli, including people, other animals, and different environments, during these weeks can greatly influence a dog's temperament and adaptability.

This sensitive period ends around the fourteen-week mark, following which dogs become less adaptable to new experiences and social interactions, making it vital for owners and trainers to focus on socialization during this timeframe. Initiating positive experiences within this period can help prevent behavioral issues later in life, reinforcing the importance of early socialization and training practices.
