Miranda Lambert's seventh annual Cause for the Paws event is landing in Sin City on Saturday (Oct. 4) for the first-ever Route 91 Harvest Festival.

The singer will headline the Saturday night show at the Route 91 Harvest Festival, which runs Friday through Sunday, and all proceeds from her appearance will benefit her charity, the MuttNation Foundation, dedicated to ending pet suffering and homelessness in the U.S. and abroad. With Lambert's help, many more sweet, innocent dogs will get another chance to thrive.

Lambert tells ABC News Radio, “I am so excited to be playing Vegas to raise money for a cause so dear to my heart. With your donations, we are able to watch happy, healthy dogs being given a second chance at life through adoption.”

The Cause for the Paws event has a host of other add-ons, including a sold-out VIP cocktail party before the country star's show, a live and silent auction with items from Lambert and Blake Shelton, and an online auction that will take place on eBay during the event.

Last year the 'Automatic' singer's Cause for the Paws raised more than $400,000 in Oklahoma, and the MuttNation Foundation has garnered a whopping $1.5 million over the past seven years.

The Route 91 Harvest Festival includes country big shots Shelton, Brantley Gilbert, Dierks Bentley, Jason Aldean, Tyler Farr and many more.

The singer is wholeheartedly committed to her four-legged friends. She's rescued dogs countless times at the drop of a hat,  and recently announced the opening of Redemption Ranch, a five-acre haven in Tishomingo, Okla. that seeks to house dogs that would other be euthanized.
