Boo, once named the "world's cutest dog," has died.
Boo's owner shared the sad news on Facebook this Saturday (Manila time), writing: "With deepest sadness I wanted to share that Boo passed away in his sleep early this morning."
"Our family is heartbroken, but we find comfort knowing that he is no longer in any pain or discomfort."
Boo, one of the most popular animals on Facebook with over 16 million followers, suffered from heart issues.
It was explained that the beloved pomeranian began experiencing health problems after his canine friend, Buddy, died in 2017.
"We think his heart literally broke when Buddy left us. He hung on and gave us over a year," his owner added.
"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."
"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."
"Thank you to all of you for following along on their silly adventures over the past 10 years. They sure had a LOT of fun."
