"Delilah was my first rescue dog, and she went everywhere," Lambert tells CMT of her terrier mix. "But she's kind of retired from the road at this point."
These days, Delilah, just one member of Lambert's ever-expanding menagerie of mutts, stays with the country crooner's grandmother. "[Delilah]'s just over it," Lambert says.
Still hanging onto their backstage passes: Cher the Chihuahua and Delta the Chihuahua-pug mix. "They're little bitty dogs," she says, "so it's easy to maneuver them."
Her furry fans are a testament to her love of animals; just last month, the singer helped launch The Pedigree Feeding Project, a new initiative to supply one pet shelter in a worthy community with a year's supply of dog food.
"Our dogs probably run our life a little more than they should, truth be known," adds Lambert, who's married to fellow country star Blake Shelton. "But with rescues, you make up for lost time. And ours have the best life now."
