Play date for young dogs

Hi, I would like my Sheltie, Gaia (1 year), to meet and play with other dogs, I am also interested into training or dog sport.I am also taking classes and starting agility once a week but would like to practice also outside. I am living in Bergerstrasse so everywhere close by or reachable by public transport would work. We are available in the evenings or in the weekend :) Looking forward to your messages !
