Bo, the Portuguese water dog and the first pet of President Barack Obama and his family, has sadly passed away at the age of 12. Michelle Obama shared the heartbreaking news on Instagram, revealing that Bo had been battling cancer. President Obama also expressed his grief, stating that the family had lost “a great friend and trusted companion.”

Bo had been a constant presence in the lives of the Obamas for over a decade, bringing joy and love to each day. President Obama took to Twitter to share his fond memories of Bo, highlighting how the dog had been there for the family through both good and bad times.

Despite the chaos of living in the White House, Bo remained a calm and collected presence, especially around children. He embraced his role as the First Dog, enjoying the perks of residing in the presidential suites and taking refreshing swims in the pool during the summer. Bo was known for his gentle demeanor and his luscious, perfectly groomed coat of hair.

In 2009, Bo became part of the Obama family when he was given as a gift by Massachusetts Senator Edward M. Kennedy and his wife Victoria to Malia and Sasha Obama. The children decided to name the dog Bo in honor of artist Bo Diddley and because they had a relative with a cat of the same name. Bo quickly captured the attention of the media and became a beloved figure across the nation.

Before Bo, it had been decades since the White House had been without a furry companion. However, during President Donald J. Trump’s administration, the White House remained pet-free. It wasn’t until President Joe Biden took office in January that pets returned to the White House with the arrival of Champ and Major, two German Shepherds. Unfortunately, Major had to undergo training recently due to some biting incidents.

Bo brought much joy to the White House press corps with his playful antics on the South Lawn, his barking during press conferences, and the messages of sympathy he received from children all over the country. His charming personality and distinct appearance even inspired a children’s book titled “Bo, America’s Commander in Leash” authored by Naren Aryal and Danny Moore. Bo’s memorable presence was also captured in a formal White House picture, where he sat proudly with his tongue out.

In 2013, Bo was joined by another Portuguese water dog named Sunny. Mrs. Obama explained that they wanted Bo to have more interaction with other dogs, intending for Sunny to be a companion for Malia and Sasha. However, Bo ended up playing a much larger role in the Obamas’ lives than they had anticipated. According to Mrs. Obama, he quickly made himself at home, strutting into their offices with a ball in his mouth, and becoming a constant source of comfort and companionship.

Bo became a part of many significant moments during his time in the White House, including the Pope’s visit and the traditional Easter egg roll on the South Lawn. But his most cherished role came when Malia and Sasha left for college, leaving the Obamas as empty nesters. Bo provided solace and support as the couple adjusted to their new phase of life, as Mrs. Obama shared on Instagram, signed by the whole family.

Last year, during the pandemic when everyone was forced to stay at home, Bo was the happiest dog, according to Mrs. Obama’s post. The family was reunited under one roof, just like the day they brought him home.

Bo’s memory will forever live on in the hearts of the Obamas and in the fond memories of those who had the pleasure of encountering this exceptional First Pet. His gentle spirit, loyalty, and unwavering presence brought joy to millions, leaving an indelible mark on the hearts of Americans. Rest in peace, dear Bo. You will be deeply missed.
