Vintage Rare Dog Family Fingurines

Vintage from roughly 70s. Got from a neighbors yard sale years ago The separate dog looks to be a different maker as the set and is not marked. The mother dog and pups are handpainted Tilso Japan. The mother dog is chained to the puppies with golden chain. Hard to find. Separate 'father' dog doesn't seem to have any flaws the 'mother has a couple scuffs and pups look perfect. see photos closely
