Selecting for or against traits when breeding
 
In light of some of the posts in the "Breeding dogs with problems" thread, I thought this would be interesting... Just quote me and answer in the quote :-)

What are genetic qualities/characteristics (be they positive or negative) that are very hard to maintain in a breeding program. In other words, genetic qualities/characteristics that are very easily lost if not carefully maintained in each mated pairing?

Strong nerves and high aggression in combination. Seems to be easier to get high aggression dogs, but with the coupled nerve strength it seems a much rarer animal

Clearly DM, and elbow/hip issues. Crazy drive seems easy enough to maintain.

I'm speculating based on what I *SEE* in the various dogs that cross my path, interaction with breeders, etc.

Really? Not one person wants to chime in?

:chime: There. :) Actually I don't know enough to chime in.

I think one of the easiest things to maintain, or to bring back in if it has become diminished, is drive. Partly because it tends to bred true for the most part from one generation to the next, and partly because high drive breeding candidates are very easy to find.

And I think the most difficult to maintain unless it is very strongly focused upon, and almost impossible to regain if lost, is sound nerve. Not necessarily in the general sense as maintaining dogs who are sound and stable from an everyday standpoint isn't difficult. But when coupled with other desired temperament traits that really stress the limits of a dog's nerve strength... like high drive, strong active aggression/fight drive, some suspicion/defense, etc...it is more difficult to maintain the level of nerve required to go along with those things.

Regarding sound nerve... so worded another way, could you describe that as a dog who can be/is very civil, very sharp, not motivated primarily by prey stimulus & drive, but yet has the clear headed-ness and strength of character to not make mistakes with the application of that civil sharpness or "lose their temper" when put under stress?
