Border Collie Breeding & Registration  

The main objective of the Society is to promote and foster, in such countries as may seem desirable, the breeding, training and improvement of the shepherd's dog. 

The ISDS Stud Book, which is published each year, was set up in the late 1940s, and remains an invaluable and comprehensive list of working sheepdogs and their progeny. There are over 300,000 registration entries in the Stud Book!

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 are recognising the value of becomming a member and registering their dogs with the ISDS!
