Duke….where is he?

For some reason a sire line based on Duke, one of the breed’s foundation dogs seems to have vanished. He remains an important part of our pedigrees but only in degree of relationship. Had we been thinking in those terms 30 years ago, we could have prevented it. As the only male going back to Leonard Seppala’s Scottty, we can only regret.

I was looking for information on Duke a number of years ago and coming up dry. Then Pam Thomas pointed me to an article in the SHCA newsletter Spring of 82 or 83. There it was, his history and a picture. I reprint here for educational purposes with all credit to the SHCA.

Luna Embarked

I recently spent some money on an Embark test out of curiosity. About four years ago I did a Mars panel on Jim Brown who is the sire of Luna. I was less than impressed by the Mars panel. Possibly it is different now as four years in a long time in a developing and competitive field. But I will tell you that my main takeaway from the Mars panel was disgust with the pictures they chose to illustrate the breed. There is a link to the results below.

The Embark test had the promise of additional information with identification of undesirable markers. A link to Luna’s test is below.

As far as I know the Siberian Husky breed has only three dam lines and three sire lines. I have representatives of all in the kennel if the pedigrees can be trusted. I have included a link to Luna’s below. It traces back through Alaskan Kennels foundation bitch, Bayou of Foxstand. I would be curious if anyone had identical markers with a different maternal line. I’m going to have to test at least two more girls. I would be interested in hearing from other people on matching up haplotype with the pedigree.

The COI calculated by Embark was interesting; 27%. I’ve included below a link to Luna’s extended pedigree with COI calculated to 10 generations. It’s a little over 12%. When I calculate on 20 generations I get it up to 22+%. If the data allows them to go back 50 or 100 generations it’s probably fairly accurate as my reading leads me to believe that the gene pool where the dogs originated was not that large. Luna was the only female in a litter of seven so I think I will test one of her brothers to see if the number holds up. That will also establish one of the male lines.

My other main takeaway from this test was the inclusion of the eye conditions under health. For some years now we’ve done eye exams of our breeding stock to find out what the drainage angle of the eye is. There are some who maintain that a narrow angle is a precursor to glaucoma although the ophthalmologist who does the test for us is skeptical. It is a factor in our breeding decisions, not a disqualifying factor but we won’t mate two dogs with narrow angles. We happened to have Luna looked at last month and her angles were good. This is reflected in the health conditions. I need to test some more dogs with different eye scores before I can put much value on the Embark results but if they hold up, it’s a big deal.

Bottom line, it may be helpful over time.
