12300 different names
Off all 303602 Border Collies
From the ISDS Stud Books
(with the number of times used of each: dog/bitch)
First list (stud books 1947-2000): April 2002
Last update (stud book 2008): May 2009
Note 1: Approximately 0.1% of the dogs have been registered with a wrong gender. This was only corrected in the database if this wrong gender could be confirmed by later use of the dog for breeding. Therefor some names below that are clearly male or female, like Meg, Nell or Ben, still have counts for the other gender.
Note 2: Although the database has been constructed with great care, some names might be wrongly spelt because some of the dogs only occur a single time in the ISDS stud books and the automated processing of the books was not completely faultless on those single occurences (also see the article ISDS Border Collie Database).
