When photographer Rebecca Leimbach gave birth to baby Harper, she felt bad that her daughter might be an only child because of difficulties conceiving. But it turns out that Harper already had a loyal sister in the family bulldog, Lola.

Lola never left Harper's side from when she was a baby. Lola protected her and helped her with daily challenges. Years later, nothing has changed, and the two are inseparable. Harper sometimes goes off on her own, but Lola is always watching her to make sure she's okay.
