No to the dog park.
He's 8 months old. They go through a really freaky period about that time where they act like they're ready to beat up the entire world but really, they're just a scared puppy who suddenly realizes there's a lot in the world that seems scary. Some people call it the second fear period. When my dogs went through it, I just tried to laugh it off 'Please don't mind my puppy trying out her big scary dog act'
When you're out and about, play LOOK AT THAT, when something he takes an interest in something you think he might react to. Venus went off on a brass statue of a trumpet player when she was in her scary dog period. I laughed Silly Venus, don't be afraid of Sgt Pepper! Then I jumped up on his platform and smacked him. The next time we saw Sgt Pepper, she jumped right up and sniffed his shoes. She also reacted to strange new style park benches, boxes blowing in the wind and definitely other dogs (NO unacceptable! Bodyblock)
As far as humans, does he really have to socialize with everyone? Maybe that's just me because I have that over the top friendly german shepherd teenager that everyone calling her a lab mix (she's black) as a puppy rubbed off on her. She's 14 months now, we've spent the last 8 months or so conditioning her that if people want to meet her, they'll ask.
