Natural Bobtails in YBMC ????

you will have to go off the back end of the papers on the foundation dogs to find out the true origin of the bobtails in that registry. the rio concho dog was bobtailed, and he was supposedly unrelated. he has a three gen. background with the foundation and was used as an outcross to the ben breeding. so its going to come through on more than one source. it just takes tracing it back further than what is recorded in the registry.
beaver's crook was another original source of the bobtails. i'm sure there were others. ben jordan has kept and bred from bobtails. the people wright received and bred dogs from are the people you should talk to if you really want to know...
