King Bhumibol Adulyadej, 88, rescued the mongrel dog from an alley. He even wrote a best-selling book about her in 2002, describing Tongdaeng as a “respectful dog, with proper manners,” who “is humble and knows protocol.” An animated film, “Khun Tongdaeng: The Inspiration,” was based on the king’s dog. The Thai news media use the polite honorific “khun” to describe the dog, a term that roughly translates to ma’am. The law protecting the monarchy seems to have not limits in Thailand. Last year, a prominent scholar was accused of insulting a king who died 400 years ago. Even the American ambassador Glyn T. Davies is under investigation because he gave a speech to foreign correspondents praising the king but criticizing the “lengthy and unprecedented prison sentences” handed down by Thai military courts on lèse-majesté charges.
