"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 brought joy to people all over the world.

No, it’s not just to make themselves look adorable. Dogs curl up in a ball when they sleep due to an age-old instinct to keep themselves warm and protect their abdomen and vital organs from predators.

"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.

"Over the years Boo met some super cool people, a lot of crazy talented people, but most of all so many kind people."

Boo's first Facebook post back in 2012 simply said: "My name is Boo. I am a dog. Life is good."

Boo became so famous that Chronicle Books approached Irene to publish a book of Boo cutest snaps.

“Boo: The Life of the World's Cutest Dog” was published in ten languages and was followed up with “Boo: Little Dog in the Big City”.

The family’s statement continued: "Our family is heartbroken, but we find comfort knowing that he is no longer in any pain or discomfort.

"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.

"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.

If you have an older dog with tooth troubles, add a little water or chicken broth to his or her kibble and microwave for 20 to 30 seconds.

"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."

Adobe Animal Hospital and Sage Veterinary Centers looked after both Boo and Buddy in their final days.

Boo passed away aged 12, leaving millions of joyful fans heartbroken in the process.
