Bo and Sunny are two of the most beloved presidential pets in recent history.

After it was made public that President Obama had promised his daughters Malia and Sasha a puppy for dealing with the election, everyone started guessing what type of puppy they’d be getting. In April 2009, the world was introduced to Bo, a 6-month-old Portuguese water dog. The breed is hypoallergenic, as Malia is allergic.

Four years later, then-First Lady Michelle Obama posted on Twitter about Sunny, another Portuguese water dog that was joining the family.

According to the Wall Street Journal, requests for the breed increased “100% in the US and 122% in the UK” from the year prior to Bo’s adoption.
