Fans of 'World's Cutest Dog' Boo devastated after he passes away

Breaking the hearts of millions with the news, owners of World's cutest dog Boo, announced on Saturday that the little pomeranian died of broken heart.

In a post shared with their over 17 million followers on Facebook, the owners of Boo said that the dog started showing signs of heart issues right after his companion Buddy passed away in 2017. "He hung on and gave us over a year. But it looks like it was his time, and I'm sure it was a most joyous moment for them when they saw each other in heaven," read the post.

"Shortly after Buddy died, Boo showed signs of heart issues. We think his heart literally broke when Buddy left us."

"Our family is heartbroken, but we find comfort knowing that he is no longer in any pain or discomfort. We know that Buddy was the first to greet him on the other side of that rainbow bridge, and this is likely the most excited either of them have been in a long time."

Boo had been a celebrity favourite as well having been clicked with former One Direction member Liam Payne and actor-producer Seth Rogen. Boo was also the star of the book titled Boo: The Life of the World's Cutest Dog. In 2012, Virgin America appointed Boo as their Official Pet Liaison.

Boo's fans all over the world mourned his death.
