Do as I did join the breed club and then ask to purchase back copies of the clubs yearbooks/Annuals/Journals. At first I bought the last 10 years in my breed, then i got the previous 10 and now with some gaps I ahve yearbooks going back to the 50s and it sure is enlighteneing seeiong all the succeeding generations of dogs, giving you pretty much a pictorial pedigree of the dogs around now.
As has been said a breeder will be more than happy to bore the pants off you explaining why they did a certain mating, what they hoped to get out of it and whether they achieved their aims.
Often you are going two steps forward one step back. Also your experience in picking pups improves once yu have seen how your own develop from puppy to old age.
I now know I kept the wrong bitch from my first litter, in fact of the four she would be the one I wouldn't keep now, but she has brede some nice offspring. By the time I bred from her I knew what I was trying to correct, which I did in her daughter, but the bitch I kept lacked a bit of substance and coat but had everything else I wanted.
I mated her to her Mums half brother, as I realised the mistake I had made when choosing her in her litter, but still wanted the qualities of her sire. The result was the best litter I had bred, but sadly no-one wanted to show any of the pups. I kept the best til last and then fate took a turn an I had her back. I knew she was special as soon as I set eyes on her again, but even then I didn't realise how nice she was.
She is now a Champion 3 times over having placed twic in the Group at Championship shows, and been shortlisted everytimne she has been BOB at a Champ show.
More importantly mated to our Imported dog (outcrss for at least 10 generations) she has produced a nice litter including my pup who won into the final of the Pup Of The Year competion run at Championship shows.
Now with that pup I ahve the choice to pursue her sires lines or4 am able to go back into the mothers lines, and of course these decisions will depend on what other breeders are doing, as to what males will be available to mate her to.
From this you can see that a breeder is often thinking at least another generation away when planning a mating.
