Mother Dog Reunites With Her 4 Puppies in Heartwarming Video

— -- A momma dog's reunion with her four puppies will leave you in tears.

The touching moment was caught on camera at the Marin Humane Society in Novato, California, and has since been viewed on Facebook nearly 3 million times.

“Yesterday, two frightened dogs were surrendered to us,” the shelter wrote on their now viral Facebook post on March 7. “Upon examining the female, we learned she recently had puppies."

The post continued: "After some detective work and a lot of convincing, our team was able to get the person who surrendered the dogs to also surrender the puppies, as they still needed their momma and were not in a safe situation. We captured the moment when sad and scared mom got to see her puppies again. Tears of joy all around at this happy reunion."

Since the mother’s name is Cora, the shelter staff decided to name her puppies after other “Downton Abbey” characters.

“[The] puppies are three males and one female so we named them Branson, Moseley, Carson and Edith,” Lisa Bloch, the shelter’s director of marketing and communications, wrote to ABC News. “All are doing well and will be available for adoption in a few weeks!”
