Dog Figurines Set 4 German Shepherd ^^ Long Tails Opalescent Rare Japan Vintage

Dog Figurines Set of 4 Erect Ears Long Tails Opalescent. The mom is approximately 5" long and 3" tall. Made in Japan. Vintage. The dogs have a similar silhouette as a German Shepherd but the dogs are all the same milky-white color so not sure what additional breed or breeds these dogs could possibly be. I have seen this set with the mother and one or two pups. I don't find any sets with three pups for sale. The last three photos show how the three pups are marked the same with Japan on the back. Very good condition free of chips and cracks.
