There are lots of Chi's in UK, and in fact a few have been winnining top honours at this years Championship shows.
If you go on the Kennel Club website you can download a form to register your bitch with the Kennel Club. On the left go down to forms, and you will see a list of forms.
Also you will be able to find a list of breed clubs if ypou go on the discover dogs section and search under Chihuaua. they are recognised as two seperate breeds in the UK long coazt and Smooth (o9r is it shortcoat?). If you then contact the breed club and visit shows, making contact wiht breeders, they will be able to give you an idea if she is of breeding quality, as you should only really breed to maintain/improve the breed :D
