On Monday evening, the newly engaged Christina on the Coast star responded to an Instagram follower who asked, "What happened to biggie!" in the comments of a photo featuring Haack, 38, her sons Brayden, 6, and Hudson, 2, her French bulldog Cash and another unnamed pup. "Due to behavioral issues," Haack wrote, "I made the hard decision to have Biggie re-homed in the best interest of my children." (Haack is also mom to daughter Taylor, 11.) Commenters added messages of support, with many sharing their own stories of animal re-homing.

Andy Cohen had a similar experience with his beloved beagle mix Wacha, speaking in May of 2020 about the dog's "occasional random signs of aggression" and his fears of what could happen around his then-1-year-old son, Benjamin. "Numerous professionals led me to the conclusion that my home is simply not a good place for him," Cohen said at the time, adding, "We still see each other, but a piece of my heart is gone."
