How close is to close in line bredings - Page 1

So as I try to lean more about breeding GSD (I do breed thoroughbreds from time to time) I see things that I have questions about. I look at trials, clubs shows etc and just start randomly see what hypothetical matings would look like from dogs pedigrees I can find here.  Here are a couple dogs (names left off because they are not mine) when mated would produce the following. 
 

Line-breeding - 5 generations

• 4 - 5............................................. in SG Berry vom neuen Lande
• 4 - 5............................................. in SG Mücke vom Oberhausener-Kreuz
• 3 - 5............................................. in V Ghana von der kalten Hardt
• 3 - 4,5........................................... in SG Bandit vom Oberhausener Kreuz
• 2 - 4............................................. in V Karn vom Fegelhof
• 3 - 5............................................. in G Iola vom Fegelhof
• 3 - 5............................................. in G Ingo vom Haus Lohe
• 2 - 4............................................. in V Chuckie vom Schloß Laer

In the thoroughbred world you could end up with a complete freak of nature that would never be caught or a horse that wont run at all with the 2-4 line breeding. 

Any thoughts on if this is a workable breeding and what it would produce or why it would not work? 

I will say for me I am not a big fan in the horse world of line breeding close.  That is one of the things I like about the Bomber Pup I have coming from Parrish is that there is no line breeding going back 5 generations

I my opinion it all depends on, 1. what are your goals  2. who you are breeding  3. and what are the qualities and faults. Inbreeding and real close line-breeding can produce some of the best and some of the worst in any breeding.  If I did a inbreeding I would never let any of them out of my yard and you should expect to cull very hard, and only breeding the exceptional if there are any.

This may be a can of worms, I hope not.

as with any animal, some dogs are more preponent than others, some positions on the pedigree are more highly inheritable for certain characteristics and it does make a difference whether a certain dog is coming in thru the dam or the sire. (x vs y--you know)  just going by the dogs listed in the above linebreeding i would expect pups to have stable nerves,
clear head, good obedience and adequate natural aggression.  (good breeding for sport--ipo/schh)  if i were able to choose, i would like to see karn in the sire line and berry coming
thru the dam.  i don't see any red flags in this linebreeding, but ofcourse, subsequent generations are going to have to bring in some new blood.

You will know when you do it!!  If the sire and dam were line bred (inbred) on the same dogs that you are line breeding them on in the mating it could not go well.  I need to reshuffle the deck with an open breeding at least one third of the time to sleep well. 

Take a good look at the first three generations real well because you will see it again if you breed.

Didn't we all chastise Hans for a brother/sister breeding? This is my own opinion but I would never breed a brother and sister, no matter how good the lines were. How many other countries is this even allowed?    Barb

I think Hans breeding was an oops litter.  He left the two dogs together in a kennel and didn't realize the female was in heat.  If I remember correctly they were very young dogs, a year or younger?  But I could be wrong about the age.

That is your opinion Vonissk. I know exactly why it's done. Your making assumptions about me. That's your choice. I've bred dogs as well and I stand by what I said. I'm not sure why you feel you need to put me down because I personally won't do it nor do I support it. But hey to each his own.
