India, Sept. 18 -- Former US President Barack Obama and Michelle Obama announced on social media the death of Sunny, one of the most recognisable "First Dogs" of the Obama White House. The female Portuguese Water Dog, who joined the family in 2013, regularly appeared at White House events alongside Bo, from Easter Egg Rolls and holiday celebrations to visits by dignitaries. Sunny, 13, died on Tuesday. "We will miss her terribly, and imagine she's with her big brother now, making sure he's okay," the Obamas wrote, referring to Bo, who died in 2021.
