Kim and Moon live with adopted dogs and cats from their home in Yangsan and to now Blue House. At their house in Yangsan they lived with several dogs and cats who were all once abandoned by their previous guardians. Among those, a dog "Maru" (, a Pungsan dog) and a cat "Jjing-jjing" (or "Jjing-Jjing-ee" ) have been confirmed to live with them at the Blue House either by the media or its official social media posts. After coming to the Blue House, a dog "Tory" (, a mixed-breed) was adopted from an animal shelter in contrast with other "First Dogs" who have traditionally been purebred Jindo dogs. They also received a pair of Pungsan dogs male "Song-gang" () and female "Gom-ee" () from Pyongyang as a gift shortly after Inter-Korean Summit in September 2018. Gom-ee later gave birth to six puppies "San-ee, Deul-ee, Gang-ee, Byul-ee, Dal-ee and Hen-nim" () named after Korean words for parts of nature - a mountain, grass field, a river, a star, the Moon and the Sun. On 30 August 2019, six puppies have been sent to Seoul, Incheon, Daejeon and Gwangju leaving their parents at the Blue House. They now live with at least four dogs and a cat at the Blue House.
