Former World's Cutest Dog Boo passed away at the age of 12

Boo, a Pomeranian that was once considered to be the world's cutest dog, recently passed away, leaving millions of fans heartbroken.

The 12-year-old dog drew his last breath in his sleep on Friday, January 18, 2019, and, according to his owners, he died of heart-related problems.

The news of his passing was shared on Boo's official Facebook page, where he had 16 million followers.

LOSING HIS BEST FRIEND

The Pomeranian was one of the most beloved animals on the internet and people were delighted to see the dog's adorable shenanigans.

But, although he seemed quite happy, the truth is that the loss of his good friend and partner in crime, Buddy, which was also a Pomeranian, left an empty space in his heart.

THE POSSIBLE CAUSE OF DEATH

It is believed that Boo died of a broken heart, even though he managed to hang onto life for over a year before dying on Friday morning.

In the statement released to fans, Boo's owners, whose names are yet to be revealed, claimed that the family found solace in knowing that Boo and Buddy finally met each other in heaven.

"Boo, we love you with all our hearts and will miss you until the day we meet again. Have fun running around with Buddy and creating adorable mischief wherever you guys go."

It was also mentioned how much joy Boo brought to people all over the world and that he was the happiest and easy-going dog they had ever met, which was why they never bothered with training.

HOW SWEET DOGS CAN BE

Boo was so famous that he even had a book released after him, titled "Boo: The Life of the World's Cutest Dog," which was released to the public back in 2011.

Dogs are known to be very compassionate animals and, just like humans, they can develop great bonds between them. Losing Buddy left Boo broken-hearted and the same almost happened to a dog named Archie.

Archie, a boxer, almost got the scare of his life after his good friend Jack played dead by lying on his back with his paws in the air and eyes closed.

In the video, which went viral online, Archie can be seen howling, barking and whining, visibly worried about his friend. Fortunately, it was all a prank but Archie certainly didn't find it funny.
