Did the Church of Scientology poison an investigative reporter's dog?

A fascinating long read in LA Magazine: "In the mid-1980s, journalist Joel Sappell and a colleague began a five-year examination of the Church of Scientology that would ultimately produce a 24-article series. It would also change Sappell’s life in ways both mystifying  and unnerving. Decades later the onetime investigative reporter investigates what happened to him." One of the things that happened to him, during that period of CoS harassment? His dog was poisoned.
