Inu hariko was placed in noble women's maternity room as guardian for mother and child. Later bamboo basket and "Den den daiko" or drum were added as charm, happiness and children's health.(bamboo basket is for "washing down illness and evilness"."Den den daiko" is for baby-sitting.) Inu hariko is omen for family bond as kanji for bamboo(竹） on the head of kanji for dog(犬） forms a kanji for smile(笑） For me this look like cat.
