Many people start out looking at buying a pup from a reputable breeder, but are put off by the price. Yes, you can find Shibas at bargain prices in the newspaper. You may end up paying many times over the cost of a pup from a reputable breeder in vet costs. My first dog was a "Bargain dog" He had Hip dysplaysia, entropian in both eyes and severe allergies. His breeders cut costs but not screening their breeding stock for genetic problems, they were just breeding pets. His temperament was also wild and he was not a good dog for a first time owner and an experienced breeder would have matched me up with a better pup had I been willing to pay a little more and wait for an upcoming litter.
If the place you are looking at has over 5 breeds or mixes, uses APRI as a registry, breeds creams, pintos, long coats or other "rare" colors, advertises "champion lines" but does not show or produce champions and doesn't do health checks on breeding stock they are not the place to buy from. There are Shibas in rescues that you should look at before you support a breeder that does not care about preserving the breed, its type and its health.
You may get lucky buying a bargain pup, but is it really worth the risk?
