Socialization

Exposing a young dog to a wide range of people, animals, places and sounds in a positive way so that new things do not frighten it.

Also called: puppy socialization, socializing a dog, socializing puppies

Socialization means giving a puppy many good first experiences with the world: different people, calm dogs, surfaces, vehicles, handling, noises and places. The point is for the dog to learn that new things are safe. Quality matters more than quantity, so each experience should be gentle, at the puppy's own pace and paired with treats.

Socialization is most effective in the first months of life, but it does not end then. Dogs need continuing, positive contact to keep their confidence.

It is not the same as letting a puppy meet every dog, which can lead to frightening encounters. Forcing a nervous puppy into a situation can make fear worse. A dog that has missed out is not beyond help, but a behavior professional may be needed. Talk to a veterinarian about safe outings before vaccination is complete.
