If you think good girl Carrie Underwood wouldn’t hurt a fly, you’d be right. If you think the country megastar wouldn’t steal hot dogs, you’d be wrong.

But it’s all in the name of being an animal lover for Carrie, who reveals to Modern Dog Magazine the one rule that she broke growing up.

“I grew up on a farm and we unfortunately lived in a place where a lot of people would dump their unwanted animals,” she says. “I would sneak out of the house with hot dogs—because no one would notice if hot dogs were missing but they might if a steak was gone from the freezer—to go and find whatever strays were outside.”

Carrie’s love for animals don’t stop at dogs. She’s also explains to the mag why she became a vegetarian at age 13.

“I quit eating red meat when I was that young. I grew up on a farm with cows, and, I mean, I bottle-fed those cows when they were calves,” she says. “At the time, I never really stopped to think about why we had them—I know that sounds ridiculous—because everybody had cows and sheep and chickens and everything. And I never thought: “Why?” Then, eventually, I realized: I can’t eat my friends.”

These days Carrie has her own four-legged friends Ace and Penny, who also double as her groupies on tour.

“That’s one of the great things about having small dogs. They’re pretty portable,” she says. “The dogs got really used to being on the road with me and they’ve really become Tour Dogs.” Pick up Carrie in Modern Dog available now.
