In the heartwarming video below, a group of beagles rescued from a research laboratory in Spain experience sunlight for the first time. The 72 beagles arrived in Los Angeles last week, after they'd been saved by the Animal Rescue, Media & Education's (ARME) Beagle Freedom Project. On its web site, the Beagle Freedom Project describes itself as a "mission to rescue beagles used in animal experimentation in research laboratories and give them a chance at life in a loving forever home." Huffington Post writer Laura Hibbard spells out the intense deprivation the puppies have suffered:

ARME's Beagle Freedom Project spokesman Gary Smith said the beagles, all between ages 4 and 7, had lived in cages their entire lives. "We've been told they lived one per cage in rooms of 10 beagles, but they never had any physical interaction with one another," Smith told the station. "They've been in kennels since they were rescued about a week ago, but aside from that, they've spent most of their lives locked up."
