Curtosy of PEOPLE MAGAZINE:    ......"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."
