Dearest friends of Boo, With deepest sadness I wanted to share that Boo passed away in his sleep early this morning and has left us to join his best friend, Buddy. 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. Since starting Boo’s FB page, I’ve received so many notes over the years from people sharing stories of how Boo brightened their days and helped bring a little light to their lives during difficult times. And that was really the purpose of all this…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. Over the years Boo met some super cool people, a lot of crazy talented people, but most of all so many kind people…friends who gave him endless love, people who prioritized his comfort over getting that perfect picture, partners who understood that Buddy ALWAYS had to be included, and last but definitely not least, the amazing doctors, therapists, and staff at Adobe Animal Hospital and Sage Veterinary Centers for the countless hours of care and dedication they poured into Buddy and Boo. I brought Boo home in the spring of 2006 and so started the greatest, most heartwarming friendship of all time. 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. 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. With love and our deepest gratitude, Boo’s humans

Buddy was Boo’s fellow Pomeranian and his best friend, who died a year earlier. Apparently, Buddy’s death left Boo heartbroken.

Boo’s humans also thanked those who followed the Pom’s silly adventures over the past 10 years and thanked them all for their love and support.
