How do I learn more about socializing my puppy with other dogs? I don’t want him to have a bad experience.

I don't really worry about my puppy meeting strange dogs because if I don't know the dog, then I have no idea what kind of temperament and interdog social skills that dog has. I prefer to teach my pup to be neutral to strangers and strange dogs. There is nothing wrong with dogs having a circle of friends but that needs to be a very specific type of dog.

As for neighbors who what their dogs to say hi to my puppy, I simply say "No Thanks, my puppy is in training." I've raised countless puppies over the years and I never let them meet strange dogs or neighborhood dogs simply because other people ask. It's up to me to protect my pup from a potentially bad experience. Socializing doesn't mean they have to meet & interact with strange people and dogs, it simply means they should be exposed to being around a lot of different people, dogs, places and things in a safe and productive way.

The proximity of the exposure will vary based on your puppy’s temperament, confidence, and level of training. I know I’m on the right track when my puppy sees a new person or dog at a distance and offers attention to me without a prompt. They are learning that new things in their environment mean rewards, play, and interaction with me.
