Disregard the post above.
I don't know anyone, and the only friend I have with dogs basically said " they have to slowly be introduced before playing with my dogs" which is the same thing my cousin told me, and he ended getting attacked over food aggression, so I'm not risking it this time.
I ended taking my puppy back to the park with the intentions of going to the small dog section to keep him socialized, but since the park was nearly vacant, I took him into the large section in which he mostly played with a 4 month old Boxer and a 8 month old Boarder Collie without any incidents.
So the way I'm approaching this is just taking him when there are fewer dogs so I have more control on who he plays with.
I want to keep my dog socialized, so I'll only come when there are fewer dogs in the park until he's old enough to play with the dogs that play rough.
