No we are not on the same page blue born is the same thing as CDA. Blue born is the breeder term for it and CDA is the veterinary term for it. The only health problems associated with blue born is in extreme cases the skin most just have hair loss. There is only one yorkie born with the blue color and that is the blue born or CDA affected yorkie. I have done tons of research on this and I will never be convinced its too separate disorders. There is still alot of misinformation about this on the internet |
