A dog widely considered to be the world's cutest has died a year after his canine companion of what his owner believes to be a broken heart. The news that Boo the Pomeranian had died was broken on the fluffy pooch's social media accounts to his 17.5m followers. The adorable dog died just over a year after best-friend Buddy, prompting owner Irene Ahn to speculate he had succumbed to sadness. A post made to his 541,000 Instagram followers early on Saturday morning read: "Shortly after Buddy died, Boo showed signs of heart issues."We think his heart literally broke when Buddy left us. He hung on and gave us over a year.
