Social media star Boo the Pomeranian dog has died at the age of 12. His owners say he had shown signs of heart problems ever since his "best friend" - a dog called Buddy - died in 2017.
"I'm so sorry for the loss of your soul dog—he seemed like such a character and a light to so many in your family. I know your dad is taking care of him until you meet again one day," said Elle.
