Miranda Lambert’s MuttNation Foundation and Tractor Supply Company have teamed up for the third consecutive year to donate more than $250,000 to animal shelters across the nation. Through MuttNation’s "Mutts Across America" program, one outstanding shelter or foster-based rescue in every state – plus Washington, D.C. and a “Wildcard” pick – are being honored with a surprise $5,000 grant. Since it's inception nine years ago, MuttNation’s Mutts Across America has supported more than 450 shelters with over $1.75 million in grants.
