Consider the 5 generation pedigrees of all Goldens who hold major AKC titles.

CH Gold-Rush's Great Teddy Bear OS SDHF appears in 31.5% of all such pedigrees.

The following table lists other Goldens commonly seen in such pedigrees. Note that
Goldens with Gold-Rush's Great Teddy Bear in their 5 generation pedigree are also related
to Misty Morn's Sunset and Cummings' Gold-Rush Charlie only further back.

It should be noted that Gold-Rush's Great Teddy Bear died when he was 7.4 years old

Most Numerous Occurrences in 5 Generation Pedigrees of Major AKC Title Holders

There were 75 Goldens in the previous list. 67 (89%) were CHs. 9 had field titles (i.e., *** or better)
(12%). 10 additionally had a WC, WCX  or **.  4 had UDs (5%).
Here we consider the 5 generation pedigrees of the 50 top producing sires and dams of major
AKC title holders . In particular, the number of multiple occurrences of the same individual in
these pedigrees.

For the Dams:
Mist Morn's Sunset occurs 7 times in Nautilus Edgehill Diamen' Ice's pedigree
Sprucewood's Chocki occurs 7 times in Goldrush's Birch of Bearwood's pedigree
Holway Barty occurs 7 times in Topbrass Pawsability's pedigree
Misty Morn's Sunset occurs 7 times in Nautilus Treasure Trove's pedigree

For the Sires:
Misty Morn's Sunset occurs 6 times in Faera's Future Classic's pedigree
Misty Morn's Sunset occurs 6 times in Asterling Go Getm Gangbuster's pedigree
Misty Morn's Sunset occurs 6 times in Asterling's Buster Keaton's pedigree
Misty Morn's Sunset occurs 6 times in Faera's Destiny Kodiak Kidd's pedigree

One might expect that the resulting COI's might be higher than for the entire dataset of
major title holders but that is not the case. Their mean COI's is a bit smaller.

42 out of the top 50 dams had at least 1 individual occurring 3 or more times in their pedigree.
The same result was true for the top sires.

Focus on all K9data pedigrees not just AKC major title holders:

In early December 2010 we took a look at the 5 generation Golden Retriever pedigrees present in K9Data. ( no
Labs, test breedings, etc.) This resulted in 239,872 pedigrees. Of these 149,584 had complete 5 generation
pedigrees. The majority of these pedigrees contained ancestors that were repeated multiple times. The 149,584
complete pedigrees contained the names of 189,871 individual Goldens. This number is greater than the number of
complete 5 generation pedigrees because some in a complete 5 generation pedigree did not themselves have a
complete 5 generation pedigree.

The following table lists the top 25 Goldens who have the greatest number of occurrences in the 149,584 complete
5 generation pedigrees (multiple occurrences within a given pedigree are individually counted).  In the top 25 there
were a number of English Goldens that were unfamiliar to us. This indicates that there are a large number of English
Golden pedigrees on K9data. Note that the only field dog in the top 25 is AFC Holway Barty OS. In the top 100,
AFC Yankee's Smoke'n Red Devil OS is 38th, Eng. FT. CH. Holway Westhyde Zeus is 60th ,NAFC FC Topbrass
Cotton OS/FDHF is 74th ,FC Windbreakers Razzmatazz OD is 77th, Eng. FT. CH. Holway Flush of Yeo is 80th,
Bainin of Caernac CD*** OS is 81th, AFC Wild Fire of Riverview CDX WCX OS FDHF is 88th and FC AFC
Northbreak Kinike Sir Jim OS FDHF is 96th.
