Lisa is right.
If you send in the registration with that name, they will send you a letter stating that the kennel name is registered and it requires a signature of the owner.
Since the main breeder of the Cambria prefix has since passed, that won't be happening
So, you can't register her with that name.
I do agree with everyone else… WHY bother with a puppy that COULD easily become fanconi affected?
You did health test your own girl...
why not just find a breeder that has health-tested their sire/dam and get a puppy from them?
Or wait and breed your girl next cycle.
If you need some reading material, I'd be happy to share with you many Fanconi articles... some I have written and some by other folks.
You may want to look closer at what it is like to live with a Fanconi affected basenji. It is NOT fun.
I would love to tell you have fun... but I think you are making a huge mistake that you could very well wish you had listened to the many voices of reason.
