We’re not talking about creating a “party animal”, but rather a dog that is “socially comfortable” in a variety of settings. As an example, your goals should include having a pup that plays well with other dogs, and is able to participate in both small and large group gatherings.
If you have a puppy, start the socialization process as soon as you bring the puppy to his new home. Introduce her to adults, rambunctious kids, other dogs, and a variety of other stimuli. Yes, even your neighbor’s cat.
For older dogs, you will need to be patient. Slowly introduce play-dates with other dogs, take a walk where you know other dogs will be present, and consistently praise good behavior.
Always remember that your dog will take certain cues from you. In the case of an older dog, it is important that YOU not become anxious or display reluctant behavior. Your dog will sense it and start reacting the same way you’re reacting.
HAVE FUN!
