What kind of dog do you have? Is your breeder happy for you to show her.
As a very wise person told me today - 'There is no such thing as a perfect dog' - every dog is going to have faults, you just have to learn how to show off their good points.
My dog is a Pomeranian, she has lack of coat, stands low on her pasterns, big ears and her tail doesnt sit against her back like other poms its like a fountain, apparently there are things I can do to improve her look...but im not sure how. she is also to long in the body and weighs a bit to much. She is on a full register.
I dont think the breeder cares, what people do with her dogs.
