Miranda Lambert makes no secret of her love for animals. Her privately owned and operated MuttNation Foundation works continuously to find stable homes for dogs in need. Though 2013 is only half over, the charity has already raised $400,000 in 2013 to help neglected and homeless animals.

The singer-songwriter often takes in random strays that she finds in need, so much so that her husband, Blake Shelton, has joked about it in interviews. In 2009 she put that passion to work by founding MuttNation Foundation, which is run by her mother, Bev Lambert. Its Facebook page reports the foundation is “a donation-supported organization working to end pet suffering and homelessness in the U.S. and abroad.” Supported by a mix of private donations and fundraising efforts, MuttNation Foundation’s goal is “to ensure that every single dollar donated assists animals in need.”

Most recently the charity has been working with local organizations in Oklahoma to help some of the animals who were displaced by the tornado that swept through Moore in May. The singer recently staged her sixth annual Cause for the Paws benefit concert in Thackerville, Okla.

“This year we were so proud to bring Cause for the Paws 6 to Miranda’s adopted home state of Oklahoma,” Bev Lambert says in a press release. “Our early decision proved to be a very timely one. Just before our event date the devastating tornado hit the Oklahoma City area. MuttNation Foundation went into full action. As a result, during the event we pledged all incoming funds via our Facebook page to the affected animal rescue and relief where we had two mobile shelter units, Pedigree food delivery and a mobile animal hospital deployed."

The Cause for the Paws event raised funds through a combination of ticket sales, a live auction, an eBay auction, raffle tickets, vendors donating their services and private donations.

“I feel so blessed to be able to continue the work of MuttNation Foundation in aiding and assisting animals in need,” Miranda states. “Aside from music, this is my biggest passion in life, and I find it so rewarding to help end animal suffering and homelessness.”
