When I did mine I had a few rejected as the KC said they were what a lot of people called their dogs, so I played with my dogs names and got Kalynta after Kalli and Winter, I had to change a couple of letters, but I really liked the end result. It's not too long and goes well with some of the names I have ear marked for any puppies I breed
The other thing you could do is an anagram of your name, my other choice was Yennep, my surname spelt backwards..... although my poor Mother-in-law didn't quite get it

Good Luck, I must say the KC was brilliant and I was on the phone a couple of times getting advice about it.

Seems like a strange way of doing things to be but thanks for clearing it up.

Not really, most registered animals (cats, horses, even cows & sheep etc) have a similar system.

They also have registration numbers, but who would be able to remember those? So.... they have to be named something, and it has to be something nobody else has used, so it does get hard to think of something new, hence the long and sometimes 'odd-looking' (to non-show/breeding people anyway) names.

In cats, the owner's prefix (cattery name) is not added afterwards (in the main UK show organisation anyway). Cats I have owned in the past included Suroshan Petit Verdot, Wendele Woodsorrel and Tianlex Lowtus Blossom. If it had been allowable, I could have added my GCCF registered prefix (Firelizard) to those, which would have given me Suroshan Petit Verdot of Firelizard, Tianlex Lowtus Blossom at Firelizard, and so on.

Cats I bred had my prefix as the first part of their name, as in Firelizard Aikea Guinea, Firelizard Framboise, Firelizard Fleurdelys.

It's the same with dogs & kennel names - except (as already said) if you buy a registered dog, you can add your own kennel name (affix) to the end.
