I'm not sure if you are up for it, but you can join our meetup group in Los Angeles, we have a couple of meetings a month, you can come once a month if you'd like and just meet people and let your pup play with other pups. We are having a holiday event at a member's house next weekend, it'll be tons of fun! Food, people, DOGS, and a gift exchange!
