NOTE - REGISTRATION RULES FOR EYE TESTING CHANGED ON 31ST MARCH 2014 - information can be found here
A central purpose of the Society is to register working sheepdogs, Border Collies, in the ISDS Stud Book which is published each year. Dogs from all nations in the world are included.
Breeders can use the Stud Books to look up the parentage and lines of any ISDS registered dog. Good dogs, of known working ability or trialling success, can be identified and sensible breeding decisions made.
That is why so many people recognise the value of registering with the ISDS and more are joining each year.
