The pedigree shows a combination of West German show lines and old English lines ('Alsatians'), with a majority of WGSL.
Gayville's Ronaldo is all WGSL, from imported parents (Batu, Farbenspiel, Lärchenhain, etc)
Alsaceroyale Best Bet (15.1% COI per KC)
Alsatian (with a few WGSL imports), going back to dogs like Delridge Camilla
WGSL with a small touch of Alsatian
Lo La Vienna
WGSL from early WGSL imports with a trace of Alsatian
The Alsatian lines are among the better ones among Alsatians. There are good kennels like Vikkas there. I did not see any names that raised flags in terms of epilepsy but the more recent kennel names are unknown to me. The high inbreeding COI of the paternal grand dam is noted, and the KC's calculations are based on only 5 generations, tmk. If you are concerned about health, you might want to contact the GSD League's Health coordinator who has studied the various lines in depth.
Idk much about WGSL. They are highly inbred as well.
The combination of WGSL and Alsatian will help a bit with the high inbreeding of both lines.
Why are you especially interested in the paternal line? Both lines contribute equally.
Hope this helps. Enjoy your puppy!
