What can i expect just from my pups pedigree/bloodline ALONE. http://www.pedigreedatabase.com/gsd/...ee/558540.html. More particularly i want to know about Xamm,Nero, and Mando on the dads side. But all information would be appreciated

i know most of it has to do with how i raise the dog and such but i just want to know what the potential is i.e aggression, eager to please etc. stuff like that just based on the pedigree alone

Thanks in advance guys
