I know some states gives breaks to people with show dogs, so that could play a part in the decision to paper your dogs. I mean gives breaks as far as registering as a kennel with the county and registering all your dogs and being legit n what not. that's a different topic on it's own, but in some cases it's beneficial to belong to a registry and actually go to the functions depending where you live and the laws of the land. some and states only want "show people" breeding dogs.
