The MuttNation Foundation, helmed by Miranda Lambert, will celebrate its 15th anniversary with a special Music for Mutts benefit concert scheduled for Saturday, Oct. 5, at Ascend Amphitheater in Nashville. The country musician will headline the show with special appearances from friends and collaborators.

“I wanted to do something special to celebrate MuttNation’s 15th anniversary and thought sharing an evening of great music with some great friends that will also feature lots of mutts would be about as much fun as anything I could imagine,” Lambert shared in a statement. The complete Music for Mutts lineup will be announced at a later date. The musician also hinted at “lots of other activities,” referencing her goal to “just make it a big party. I hope everyone will come out and party with us.”

Proceeds from the event will benefit the MuttNation Foundation, which Lambert co-founded with her mother in 2009. During that time, the nonprofit has focused on distributing money to animal shelters in need. Music for Mutts will also feature an adoption event to find homes for sheltered dogs.

“MuttNation’s mission is to support the adoption of shelter pets, advance spay & neuter, and educate the public about the benefits of these actions,” a mission statement on the foundation’s website reads. “MuttNation also works with transport partners to assist and relocate animals during times of natural disaster.”

General sale for the Music for Mutts benefit concert will begin on Friday, May 10, at 10 a.m. CT via Live Nation.

Earlier this month, Lambert dropped her new song “Wranglers.” She debuted the track during her headlining performance at Stagecoach Festival, a set that also included surprise guest Reba McEntire.
