Harrowing news today.

Boo, the world's cutest dog, has tragically passed away. The 12-year-old Pomeranian lost his best friend, Buddy, a year ago and since then, his owners noticed that he was beginning to experience health related issues. Boo died on January 19, from what his owners suspect was a "broken heart." They broke the news to their millions of Facebook followers over the weekend, saying that now that Boo and Buddy are back together, it's "... likely the most excited either of them have been in a long time." "Our family is heartbroken, but we find comfort knowing that he is no longer in any pain or discomfort," they said. "Boo brought joy to people all over the world. Boo is the happiest dog I’ve ever met. He was so easy going that we never had to bother with training. "He made the manliest of men squeal with delight over his cuteness and made everyone laugh with his quirky, tail wagging personality." Boo's humans brought him home in 2006 and since then, they have witnessed him running around, playing loads, and generally making everybody else's lives a little better. "We think his heart literally broke when Buddy left us," they said. "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." In their post, the dogs' owners thanked Boo's vets for the hours of work and dedication they paid to both dogs, and hoped that the two dogs were together "creating adorable mischief wherever you guys go." May they both rest in peace.
