Puppy Socialization Checklist
A well-socialized puppy creates a behaved, relaxed, safer dog. If your puppy is comfortable in a wider variety of situations, they're less likely to use aggression in moments of fear.
Try to avoid doing too much too fast. For instance, if you want your puppy to get accustomed to being handled by multiple people he doesn’t know, start with a few family members and slowly integrate one stranger, then two, and so on.
Most importantly, when introducing all of these new experiences to your puppy, make sure he’s getting an appropriate amount of treats and praise, so that he associates what he’s being exposed to and the feeling of seeing something new as a fun experience.
