Four Porcelain Vintage Dogs, Made In Japan

Description

Four Vintage Dogs, Made In Japan. Condition is "Used".
I bought there many years ago, probably from an estate sale, and never displayed them.
They have like a mother of pearl finish and looked like a German Shepherd to me. But could represent a few different breeds.
No chips or cracks.
I think they are porcelain because they are very light
All marked Made in Japan.
