Greg introduced Blossom in the August 2019 video "Brooke Houts & Her Dog". In the video, Greg says they adopted Blossom from a shelter and suggests viewers should adopt through shelters. (video deleted) Some viewers found this hypocritical as Greg and Kai recently dropped off their dog Caterpie to a shelter after adopting her through Craigslist.
Some controversy arose after viewers realized Greg recently uploaded a video of himself shaving a white dog, who they believed to be Blossom. ($ource) Some viewers were upset as the type of fur Blossom has should not be shaved. The dog in the video was actually Greg and Kai's dog Dobbs.
After the initial introduction, Blossom has not been featured in any other videos. She could sometimes be seen in videos walking around their home and backyard. Unlike their other dogs, Greg and Kai do not feature Blossom on their social media. Dobbs and LeeLu especially had many photos posted of them to their social media.
