The cubs, named Chira, Batari, and Izzy, enjoy the dog's company because she provides snuggles and comfort.

Although Blakely has quite a task on her hands, she is no stranger to serving as a nanny. She has watched over other zoo babies in the past, including cheetahs, a warthog, wallabies, skunks, and bat-eared foxes.
