@beth314 If you have the registration number it is possible to obtain a few details from the AKC website. But these are limited to date of birth, sex, color, titles and possibly microchip. But nothing in the way of parents, breeder (although the Affix or kennel name will be a good indicator) or owner. If you are posting @tanza privately, give her the registration numbers - or email them to me. We can do some digging.
You can get test results (if any) from OFA with the registration number bit this is also a bit iffy. So many people fail to give a registration number and there are always lots of 'Puppy #1' and 'yellow', 'green' etc named pups !
As others have told you, if the breeder has not tested the parents, steer clear. This is not a reliable, responsible breeder and if it later transpires your puppy has a serious problem, you will get nowhere. The contract is not worth the paper it is written on.
