This is a vintage used Arnart figurine designed by Erich Stauffer marked 55/1957 with a Crown mark.  It shows a boy wearing bib overalls and a scarf brushing a pet dog sitting on  a stool.  It is about 5" tall.  This is made in the style of a Hummel, but it is not a Hummel. Arnart sold these figurines from the '50s to the '70's.  It was probably made in Japan.  There is no original box.  See the photos.
