Then by all means, proceed with the planned breeding.

I'm not the OP. I can't ever imagine doing such a breeding for all sorts of reasons. I can't imagine ever buying such a pup, either.

I'm just saying that the handler aggression trait shows up in GSD with strong 4th Line genetics and that it isn't necessarily a bad thing, but the vast majority of people do not like it or have a good use for it.

It's important to me to know if someone means aggression in the sense of handler aggression or GSD protectiveness/civilness or working line temperament and comparing with poorly bred or popular pet GSD without temperament/drives that's part of the breed standard that might lick a burglar to death.
 

Handler aggression isn’t necessarily a bad thing? When is handler aggression not a bad thing? What use does someone have for handler aggression?

"I'm just saying that the handler aggression trait shows up in GSD with strong 4th Line genetics and that it isn't necessarily a bad thing,"

Just curious-
What is 4th line genetics?
When is handler aggression not a bad thing?

No one knows how a specific litter will turn out until it's done but I don't recommend doubling up on Bolle because he throws very sharp dogs and I anticipate you getting a lot of returns. Bolle is a very nice working dog but more is not more with him. 1-3 is way too close you are asking for health and temperament issues. Just my opinion.

From a post of mine a couple years ago in a different thread:

There are several posts on pedigreedatabase by Prager that are very informative about linebreeding and the traits of the different German Shepherd lines.  Here's a discussion of bloodlines on pdb.  The first post on page 3 by Prager briefly lists the specific characteristics of the different lines  http://www.pedigreedatabase.com/german_shepherd_dog/community.read?post=857657-german-shepherd-bloodlines&p=3

 

FWIW, my dog is mostly Line 2 and Line 4, and a little Line 5.  She strongly exhibits identifiable, specific traits of Line 2 and Line 4, and one specific identifiable trait of Line 5.  For the purpose I got her for, she's about as perfect as could possibly be (THANK YOU, Sarah!).  She's also very versatile, so was able to train her for something else when circumstances changed (THANK YOU, again, Sarah!)

 

Did Bolle get his aggression from his mother Bora Excalibur Europa?
