My husband and I are planning a roadtrip to Big Sky in the beginning of July. We are bringing our very active Portuguese Water Dog with us who loves to join us on all outdoor activities (he even has his own backpack!) How dog friendly is Big Sky these days? We already have a place to stay, so that's not a need. I basically need advice on good dog-friendly trails for hiking and/or mt. biking, places where he can swim, restaurants with dog-friendly porches, stores that allow dogs, etc.
