"I have two small dogs, Delta and Cher, so they are usually the ones who go on tour," she told PEOPLE.
Though sometimes, it's not always her the dogs want to be with.
"Betty is one of our dogs that we take on tour with us as well, but she's kind of a daddy's girl," Lambert said, "so she hangs out with Blake a lot."
But while the couple's pooches tend to play favorites, the Grammy nominee says she has no such preferences, referring to her home as a "full-on farm." "I have a huge passion for rescuing animals," she notes.
That attitude is part of why on Jan. 23 in Glendale, Calif., the singer helped launch The Pedigree Feeding Project, a new initiative by the company to supply one pet shelter in a worthy community with a year's supply of dog food. And having rescued a shelter pup herself, Lambert personally understands the campaign's importance.
"I have a Chihuahua that I got at a shelter at 4 weeks old and I have to remind her of her roots," she said. "I tell her that she did not grow up in Bel Air. She came from a shelter in east Texas. I have to keep her humble."
