A tear was shed around the world this week when it was announced that Boo, the world’s most adorable dog, passed away in his sleep Friday.
The 12-year-old internet sensation was subject of several books and merchandise with over 16 million likes and followers on Facebook.
His older brother, Buddy, had passed away in 2017, and their owners swore that Boo passed from a broken heart.
“With deepest sadness, I wanted to share that Boo passed away in his sleep early this morning and has left us to join his best friend, Buddy,” his owners wrote on Facebook. “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.”
His humans said that when Buddy passed away, Boo began having heart issues after his brother died.
“We think his heart literally broke when Buddy left us,” they wrote.
