When do Kyi-Leos stop growing? When do Kyi-Leos stop growing?
Kyi-Leos stop growing between 10 and 12 months of age. Like most small dogs, they reach their full height and weight earlier than larger breeds. Although they might continue to fill out or gain some muscle mass after 12 months, their major growth in terms of height usually slows down by the time they are around one year old.
