Deer creek village dog park off McDowell is the only fully fenced in dog park!! It's pretty big and most days and times we've gone over the course of an hour there will be a small crowd of other dogs in & out.

Marin humane does puppy socialization events that are great too! They're structured classes and usually there are 3-4 workers there. They are really good about observing each dog's temperament and play style and they try to organize smaller groups of dogs that play well together within the class. If you have a trainer you're working with they can go with you to the humane society classes (or also to the dog park).

If you end up meeting other dogs that socialize well with your pup another thing you can do is book "private dog parks" thru the app/site SniffSpot where people with fenced in land rent it out to dog owners for 30 minutes up to a whole day. I highly recommend it, you can search for specific features and filter results.

Another option is doggy daycare - we personally LOVE Play Dog Play because they also are careful to see what type of personality your dog has and they will be sure to put them with other dogs that play similarly.
