There is nothing wrong with having and breeding unregistered stock. These are dogs that have handwritten pedigrees and that is just the same as a ukc registration paper that has a ped. These are not dogs with unknown peds being bred. Now I speak in general not about my personal dogs here. I know how you like to make asumptions.....
People paper hang all the time look at what happened to the gotti and RE line!
If you have registered stock then I think you should keep up with the paper trail but not all breeders do.
You had said that you can only show a dog with papers in show and weight pull. Not true. Maybe conformation but WP can be done by many venues without a pedigree from UKC or ADBA. You can also compete in Agility, Obedience, and rally in different venues without being fixed and with no registration.
UKC, AKC, ADBA, it's all about the money and not that I do not participate in those registries (I am the president of a UKC club) but it is not the end all be all. Your opinion is just that, and many do not agree with you. You try to lump BYB in with dogmen who did not register dogs.
Look at the GSD
, Mal's or Dutch's. Dogs are being imported from Europe with handwritten peds or peds that will not be recognized in the US. I work closely with police dogs and Schutzhund dogs that we important and train for police work. These dogs are mostly unregistered for one reason or another and come from HUGE working kennels in Europe. Are these dogs not worthy of breeding because they do not have AKC papers? Bull Sh$$ Dogs with no registration are being bred all the time for working dogs. They are being imported/exported and no one is calling them BYB's. It's just they way things are sometimes. So you can think that only responsible breeders will register dogs with UKC, AKC, ADBA but truth is many dogs and breed are not being registered because it is not a big deal as along as you are keeping track of records with hand written peds.
I think that if dogs have registration you should keep up with it but if not I am not one to say you are wrong.
This has nothing to do with BYB's that a whole different can of worms.....
