The first one is an old, very small hand stitched toy with a string to hang it as a decoration. It is the same basic pattern as a traditional sarubobo monkey doll.
Next is a panel of wool mosu ('muslin') with nationalistic symbols and scenes typical of many boys' kimono and men's nagajuban undergarment fabrics in the 1930's.
This little wooden ornament is a Tosa fighting dog from Kochi prefecture in it's full regalia (not that I want to endorse dog fighting!)
From a roll of children's yukata fabric, probably 1960's:
One of the most well-know traditional Japanese dog images is the paper mache ' inu hariko' (though a lot of people mistake it for a cat!)
Because of the ease with which dogs give birth the inu hariko has traditionally been used as an amulet for safe and easy childbirth. The following image is from a very old manual for women (circa late 18th century) and gives instructions on preparing the expectant mother's room, including placing an inu hariko in the room.
