i brought a german shepherd bitch at chridstmas from my sister in law whose gs had a litter from another pure gs??
unfortunately neither mum or da are kc registered yet they are pure german shepherd breed.
The pup i have i am not bothered aboput papers yet i find that i wont be able to show her in open or champ shows?? what can i do if anything

Unfortunately you won't be able to do shows except for Companion Shows.  These shows though are really good fun, you have pedigree classes, which as you dog is a purebred you can still enter in and then you have the novelty classes, such as dog most like its owner, best six legs, most handsome dog etc.  They are really great fun.

If the parents arent registered then pup cant be either

If you are interested in Obedience/Agility/Flyball, you could register her on the working register & compete in those - much more interesting for the dog! You can also take her to training classes & get some experience in all the above as well as showing - might find out you prefer competing in something else.
