A study of the occurrence of GRCA Outstanding Sires and Outstanding Dams in Golden Retrievers

Consider a group of Golden Retrievers who hold at least 1 major AKC title and whose 5 generation pedigree in
K9data is complete. The following histogram details the number in each pedigree that were either an OS or OD. The
mean number is 34 per pedigree. However, as shown below, the number of OS and OD per pedigree has been
increasing over the years. The following assumes that K9data pedigrees are correct.

CH Goodtime's Maine Squeeze OD has the largest number -> 62 out of a possible 1 + 2 + 4 + 8 + 16 + 32 = 63
Major AKC Title Holders with no OS/OD in a 5 generation pedigree

Golden FCs sorted by OS/OD numbers in their 5 generation pedigrees

Golden MHs sorted by OS/OD numbers in their 5 generation pedigree

Golden OTCHs sorted by OS/OD numbers in their 5 generation pedigree

Golden CTs sorted by OS/OD numbers in their 5 generation pedigree

Golden MACHs sorted by OS/OD numbers in their 5 generation pedigrees

Golden CHs sorted by OS/OD numbers in their 5 generation pedigrees
The following table shows that the OS and OD numbers per pedigree have been increasing
but the percentage of OS and OD Goldens born in each decade have not. Goldens in the
last decade have not had much of a chance to produce many titled offspring.

The OS and OD titles are not used outside of North America. Thus the histogram for OS and OD numbers in a 5
generation pedigree (based on K9data) shows many lacking and OS or OD ancestors.
