This short story from the collection Wild Child was originally published in Harper's and selected for The Best American Short Stories, 2008 by Salman Rushdie.
In high school Nisha worked as a dog-sitter for the Strikers, eccentric millionaires, taking care of their prized Afghan, Admiral. When she returns after college to tend to her ill mother, the Strikers call on her once again. But this time they want her to take care of Admiral II, the clone of their deceased dog. The original Admiral's experiences must, of course, be replicated as closely as possible.
