HOW DO YOU GET A KENNEL NAME AND HOW MUCH DOES IT COST ?ALSO HOW MUCH DOES IT COST TO CHANGE YOUR DOGS NAME THAT IT WAS GIVEN BY THE BREEDER MY IT HAS NOT GOT AN AFFIX ,I AM A MEMBER BUT IT WONT LET ME LOG ON SOMETHING ABOUT COOKIES

As far as I'm aware you cannot change the name your dog was given by the breeder.You can apply for an Affix through the kennel club  but that's something you would only do if you were to become a breeder.You still wouldn't be able to change the name of the dog you have to your chosen affix but would be able to use this affix on any pups you breed.
Hope this helps

It's possible to change a dog's registered name, but only under certain circumstances. This form explains the rules.

If you were to apply for an affix yourself (details on the KC site - cost about £100 I think, plus an annual fee) you would be able to add your affix at the end of the dog's registered name.
