Socialization is NOT about just tossing your puppy into the mix to sink or swim on their own.
It is a chance for your puppy to learn, with your support, that the world is full of awesome things. Support does not mean pushing your puppy into situations they are afraid of so they can learn it won’t hurt them. But it is about helping your puppy explore the world in a safe way.
Providing support can look different in different situations. Usually it means being present for your puppy to ensure your pup isn’t overwhelmed and encouraging your puppy to try again. Providing treats, comfort, and play as required. Provide treats when your puppy is calm or offering polite behavior like sitting to greet a new human. Provide comfort when your puppy is worried about something. Comfort is different to every puppy but most pups like being close with a hand on their shoulder or chest rubbing slow soothing circles. Pups usually don’t like being patted on the head or back when they are worried. Play is super helpful when your puppy is comfortable in a new situation to allow a puppy to learn about how they fit in the space.
So how can you make sure to do all this when you can’t really introduce your pup to ever other dog and person you see?
