From the Kennel Club website:
To allow the registration of your Greyhounds, they would first need to be registered with a Racing Greyhound Society. The certificate and pedigree information will need to be sent with a Form 9 application. This application can be downloaded directly from our website www.thekennelclub.org.uk by clicking on the 'Working With Dogs' header on our homepage. You will then need to scroll down to 'Kennel Club Forms'. Alternatively we can send these applications through the post, however we require your full address details to do this.
The fee for this service is �12.00 per dog.
This application will state for Border Collie, however if you simply cross this through and write Greyhound, we will still be able to assist you with your request.
If we can be any further assistance please do not hesitate to contact us.
