I have a picture of Carmspack Allycia UD just celebrating her 14th birthday romping in the with a bunch of family golden retrievers much much younger than her. The owner trials them and has a number of Master Hunter titles on the Goldens . The GSD is still the queen , still in charge , still youthful in attitude although hearing is becoming selective and eye sight starting to be less than .
She underwent a procedure for some damage to her knee . It was recommended , since she was "under" for the x ray to also do an x ray on her hips and spin.
The report was no arthritis on hips or spine , no disorder on spine -- CLEAN , and hips to quote "still tight as a tick" . At 14 .
pedigree represented by her brother Sensei who passed away at age 13 .
Carmspack Sensei - German Shepherd Dog
Kilo was over 13 years of age , Kilos sister owned by Linda Shaw saw as many years plus some -- Addi Tonteichen was that age (will have to check into that).
I had the pleasure of writing the Seidler family , THE breeders of vom haus Iris . Gunther Seidler told me that Rex Iris passed away at age 14 as reported to him by Adam Kuhn, as did the dam Mira haus Iris , Ulf Iris I believe was 13 or 14 also.
Longevity runs in these lines. But this goes far beyond longevity because the dogs are in carefree rugged health to those last days .
There is so much more to understand in genetics than basic mendellian mode . Epigenetics, how outside influences change genes --- big one.
A book I would recommend highly is POTTENGERS CATS that shows the effect of flawed nutrition through generations . This book has been unavailable for decades due to a problem with the estate that inherited the works . 'Finally the problem is resolved and the book is back in print , in limited numbers. I jumped at the chance and bought a few.
more later running behind already
