Pedigree Study of Recent Top Golden Retriever Obedience Dogs
If one is thinking of looking for a future top obedience prospect what might be learned from the pedigrees of those
Goldens who have recently have such success? Here we will consider 4 groups:
1) Those who have been among the top 10 in terms of OTCH points: topOTCH
2) Those who have qualified for the NOI 2009-2012: NOI
3) The oldest Golden in the 2nd group was born in 1999. So now consider those Goldens born after 1999 who
hold an OTCH but did not qualify for the NOI: noNOI
4) Finally, a random group of Goldens born after 1999 who hold major AKC titles but lack any obedience titles:
In following histograms show that each of the above 4 groups do exhibit differences in their pedigrees. Note that this
is only a difference in the mean numbers and that there are certainly individual pedigrees that differ greatly. Note
the importance (generally) for a strong field background.
The following table lists the title count breakdown for each Golden in the 4 groups. I have included Canadian
titles. The titles of the Goldens in each group are not included in the count, only those of their ancestors.
Now consider what ancestors appear in the pedigrees of these 4 groups. Are ancestors holding OTCHs more
frequent or those holding advanced field titles?
The most common ancestor in the topOTCH 3 generation pedigrees was Locknor B Fifty-Two Bomber (a
Reggie son). Meadowpond Startdust Reggie was 4th. In the 5 generation pedigrees, Yankee's Smoke'n Red
Devil occurred most frequently. In the NOI group: Reggie occurred most commonly in 3 generation pedigrees
but was absent in 43 out of 60. Yankee's Smoke'n Red Devil topped the 5 generation list. 96% of the no
obedience group lacked Reggie in their 3 generation pedigree.
Note that the Golden with the most OTCH offspring is Meadowpond Startdust Reggie.
In a 5 generation pedigree there are 60 possible ancestors. In order to see how similar a pair of pedigrees are
we might count the number of Goldens that appear in both pedigrees. The following table lists results of
pairwise comparisons within each group. Within a given pedigree we might like to see what fraction occur more
than once within that pedigree. As expected, the topOTCH pedigree resemble each other more closely than
randomly paired pedigrees.
|Mean number of common
ancestors for pairwise pedigree
|Percentage of pedigree
pairs with no common ancestors
|Mean number of ancestors for a
given pedigree that occur only
once in that pedigree
Earlier, we looked at the number of occurrences of Goldens grouping all pedigrees together (within each
group). However, some Goldens often occur multiple times with a given pedigree. Now just count the number of
pedigrees containing that Golden without regard to the number of occurrences.
