Walk/ play with potential friends

We have just gotten our Finnish Lapphund puppy and would love for him to meet and get to play/ walk with other dogs so that he can have friends.
He loves to play and can be a bit shy at first.

Although there are many dogs in Munich, not many are available for a walk or play with a puppy. We would love it if someone is interested so that he does not grow frustrated to not play with other dogs :)
