Yes about 2 years ago my friend had a Blue born Yorkie . It died at the age of 9 mths old. They took it to the vets office for a check up. Five days later he was dead. He was fine when they took him to the vets office. They still don"t know what happened to him. They say it was because he was a blue born. They never bred there Yorkies again. They got both parents to this puppy fixed. So some blue born have problems and some don"t I believe. They were just unlucky and the puppy was too. So sad.
