Brody, 35, shared an Instagram story of their dog Shoey making a funny face.
The former couple adopted the pup in November 2014.
Kaitlynn, 30, spent her Friday night partying at the Sunny Hill Festival in Kosovo, where acts like Miley Cyrus took to the stage.
Brody might have been trying to find some humor in his life amid the news about him and Kaitlynn breaking up.
US Weekly confirmed their split on Friday, August 2, one year after their wedding ceremony in Bali, Indonesia.
The couple were never legally married because they never filed for an official marriage license in the United States.
They were together for six years before calling it quits. Kaitlynn has already moved out of the Malibu home they shared.
The last time either of them posted about each other on social media was in June 2019.
