I agree with Britster, but I wouldn't take Miloh to dog parks just yet. Kaji has been punked there before. Although he is much bigger than Miloh, in both size and age, he too had to be picked up for his own protection. At dog parks, dog beaches, you get a mix of good and bad. Most of my experiences have been great! Just once in a while one dog won't leave Kaji alone, and the owner does nothing to control their dog. We've left before because Kaji was just having a horrible time.
If you can, take him out with dogs you know what their temperaments are. It helps socialize him in a controlled environment. When he's bigger, knows how to be around other dogs, and his confidence increases, then take him to doggy parks. Remember Adi and her dog Missy? Missy was pushed around at a LA dog meetup and that made her scared of other dogs. Adi worked hard to build her confidence back up, taking her to play with other dogs in a controlled environment, and now she's happy to play with any dog.
By the way, which dog park to do you take him to?
