Well now I tried to research the lines online which I really had no luck but my breeder had done some research on her babies and was kind enough to pass it on.I have found it to be easier and you are less likely to pull out your hair if you just let akc do it for you I think it is like $12.00.I am 10 generations in on Katie's pedigree thanks to her breeder and 7 back on Snuffy so far the only complaint I have is it is sometimes hard to follow the pedigree with the format at least for me I hope this has helped and good luck researching
