Dog Welfare and Puppy Socialisation Science

The socialisation window in puppies closes around 12-14 weeks. Evidence shows that appropriate early experiences during this period profoundly shape lifelong welfare.

Key Facts

The sensitive period for socialisation runs from approximately 3-14 weeks
Positive experiences with people, animals, and environments during this period create resilience
Under-socialised dogs show higher rates of fear, anxiety, and aggression
Puppy classes and controlled socialisation experiences improve long-term outcomes
Breeder socialisation before 8 weeks is as important as owner socialisation after collection

Welfare Considerations

Puppy socialisation quality during the sensitive period has lifelong welfare consequences. Investment in appropriate early experiences prevents fear and anxiety disorders that cause chronic welfare harm.

What You Can Do
