AUSTIN, Texas (CBS SF) — A smartphone accessory firm has a plan to save battery-drained attendees at the South by Southwest 2015 festival by sending them a rescue St. Bernard dog carrying a reserve battery pack.

Orange County-based Mophie is teaming up with a rescue group to provide the dogs known for saving people in the Swiss Alps. The St. Bernard Rescue Foundation said it hope to get attendees to adopt them from their organization after the festival.
