In her last months, Sato's blog showed Kabosu being fitted for a walker and pushed along in strollers. She still went to the kindergarten.
In February 2024, Sato told the Asahi Shimbun that ever since Kabosu came home, "a series of miraculous things" had happened, filling her life with priceless moments.
On March 19, 2024, Kabosu was photographed napping in Sato's office after playing with the children. She was about 18, far older than most Shiba Inus live.
