Ways to socialize your dog

Here just some visuals about what socialization can look like. Take your canine friends with you to expose him/her to a variety of situations. Invite people over and teach him the way you would like them to behave towards visitors. Do this often, at least daily throughout puppyhood and adolescence. There are special requirements if you are going to train a service dog or specialized working dog. This is  your good canine citizen kind of socialization which ideally every dog should get who lives in the vicinity of other people and 4 legged creatures...and a good basis for all dogs. IMPORTANT: you must be in control of these new experiences to keep them safe and fun, building healthy confidence in your dog, as well as a trust based relationship between you and your dog. YOU must be in charge to keep your puppy safe. For example - letting your dog loose in a dog park so he/she can "socialize" with other dogs may severely backfire if you don't know exactly the other dogs it will meet.
From Minette on dogtrainingsecrets.com:
.... young dogs and puppies are forming “opinions” about their world and they need socialization with lots of other “good” dogs so that they can generalize “all dogs are good” but once the dog is mature and likes other dogs this generalization has hopefully already formed and you don’t need to continue to socialize with unknown dogs.

Socializing your dog: It is fun, it is bonding and it can prevent a world of trouble later on.You will never regret the time and effort you spent doing this for your canine friend
