Does anyone know if it's possible to adopt/rescue a purebred dog?

I love shiba inus and Welsh Corgis. But I’d much rather adopt or rescue a dog than buy it (Beside the fact that I’ll never be able to afford it). Is there anyway to rescue a purebred? I don’t know much about this kind of thing, I got my last dog at a soccer game when a woman came around with a box of puppies that she found behind a Ralphs. She passed away about a year ago :( and I miss having a furry friend around.
