I work at a dog training facility that also offers daycare (which is the area I work). It also offers "open play time" on certain nights.
For example, on Friday nights from 5-6pm puppies and dogs under 20 pounds and play, 6-7 any dogs over 20 pounds that have a soft or moderate play style play, and from 7-8 any dogs over 30 pounds with a rough and tumble play style come to play. All dog's and puppies need to have their 5 way, kennel cough, rabies (if under 6mos) and negative fecal sample or dewormed within the last 6 mos in order to play.
Maybe look for a training facility or daycare, or doggie fun group of some sort in your area and ask if they offer controlled social play groups like that.
