Puppy socialization

Socialization means introducing your puppy to a variety of new things in a positive way, helping them feel comfortable and adapt to each new experience.

So what does improper socialization look like? Dogs who haven't been properly socialized tend to be shy and over-reactive. That reactive behavior happens because the puppy was never positively exposed to environmental stimuli. Fearful puppies might flinch, freeze, or withdraw when petted. They might startle easily at things considered routine: loud sounds, moving bikes, automatic doors, people of different shapes, sizes, and ethnicities.

The window opens long before your puppy is yours. It runs from roughly three weeks to about sixteen, and the part that belongs to you starts the day they come home.

• Before 8 weeks the litter does the work. A puppy should not leave their mother and littermates before eight weeks: that is where the first and most important lessons about being a dog are learned, and in most states it is also the law.
• From 8 weeks it is your job, and you have about eight weeks of it. This is when new people, places, sounds and surfaces are absorbed most easily.
• The window closes gradually around sixteen weeks. It does not slam shut, but nothing you do at seven months buys back what was easy at ten weeks.

The 8-to-16-week stretch that's yours to work with lines up with what the developmental stages guide calls the socialization period (8 to 12 weeks) followed by the seniority classification period (12 to 16 weeks): two names for two parts of this same window.

• Start before the series is complete, in controlled settings you choose.
• Carry your puppy in busy public places rather than putting them down on ground every dog walks on.
• Pick known, vaccinated, healthy adult dogs for introductions, and friends' clean gardens over dog parks.
• Dog parks, beaches, trailheads and pet-store floors wait until your vet clears your puppy.
