If you agreed to put her kennel name in the deal, then it should be there. Wherever your dog's full name appears it is advertising her kennel and should. Some people are way big on that. Other people, go back in their dog's pedigree and use a kennel name they like. This is a problem too because if that dog is unsteady or has a problem, it reflects negatively on that kennel that did not produce the dog even if it did have a dog back there.

Some breeders are a lot more anal about it, and will actually register all the dogs themselves to ensure their kennel name is on the dog. Others go by asking the owners to do so, and if they agree, that is fine.

Unless she might not have sold you the dog if you did not agree, I do not think she should be too crazy about it and certainly not as rude as you say. I mean, breeders ask their buyers and get assurances by their buyers of a number of things they never do. Like attend obedience classes with the dog, feed a good food, not let the vet give it the vaccinations over again.
