The backmassing on Jeck is stronger than the backmassing on Fero...the dog did not have good hips....when 6 dogs in the 3rd and 4th generation are linebred on the same dog - that is backmassing and it can be strongly influential...even if the dog is in the 8th or 10 generation....
I came from being a student of Thoroughbred pedigrees and breeding...strong female families, long term programs over 10-12 or more generations, usingg "nicks" and identifying where issues originated are very much a part of looking at TB pedigrees....looking at a sales pedigree, the female side gets examined far more in depth than the male....the big prices go for horses with solid connections to production from female families.
That being said - it is nearly impossible to find showline dogs NOT backmassed on Jeck.
