Lester Nider, a doctor in adult medicine at Monroe Clinic, spends a lot of time walking with his best friends - Luna, a 7-year-old catahoula leopard dog-beagle-blue heeler mix, and Lola, an 11-year-old border collie mix. Nider got Luna from a rescue organization in Arkansas after finding her online and then got Lola from a rescue in Madison so that Luna would have a companion. While Lola kept her shelter-given name, Luna's name was originally Bubbles, which Nider didn't want to have to call out, so she was given the name Luna instead.
