- I just thought I would add my 0.02 to this thread. First of all,
- there is an interesting discussion of the "breeding for conformation
- v.s. breeding for ability" quandry in the book _The Dog's Mind_ by
- Bruce Fogle. In the first chapter, he discusses, among other things,
- a study done by Dr, I. Stur, University of Vienna Animal Genetics Institute.
- He investigated performance traits of 62 German Longhaired Pointers (never
- heard of this breed before). 21 different conformation and temperment characteristics
- were classified by experienced dog judges. He observed a negative correlation
- between "form value" (breed standards) and "constitution". Stur argues that
- by selective breeding only to morphological breed standards, we unknowingly
- breed for similar genes at gene sites or "homozygosity." And unwittingly,
- as we breed for homozygosity to conform to breed standards, we also breed
- for homozygosity in the genes that affect behavior.
-
- This research showed that pointers which were more likely to win at dog shows
- were less likely to function in the field as pointers. Stur says that there
- was a negative correlation between shot proofness (the opposite of gun shy) and
- hunting passion (which I find highly subjective -- perhaps a hunting type
- can elaborate). He suggested that shot proofness could be used as an indicator
- of the calmer and more obedient dog and could be a worthwhile factor to include in
- judging whether a pointer would make a good pet.
-
- Fogle goes on to discuss the Golden Retriever, and states that there is a distinct
- difference in the temperment of the show golden and the working lines of the
- breed.
-
- In my opinion, this can be boiled down using the following analogy. Lets say
- we wanted to create a new kind of computational platform, one that would be
- used for the solution of complicated physical problems. If we were to
- approach this problem by creating a computer based on an existing computer,
- and did not actually test it on the problems of interest, it may or may not
- perform as we would like. I mean, it might look very impressive and on a
- limited set of simple and carefully taylored test problems it might perform
- wonderfully, but when applied to a real problem it might fail miserably. Why?
- Because the "end game" was not considered in its creation. It was created
- based on what we thought a computer like this ought to look like.
-
- I realize that dogs are not computers, but when we breed dogs based on what
- we think they should "look like" in order to accomplish a given task, without
- actually seeing if they can, we are in effect, ignoring the "end game" as
- in the above analogy, and are increasing the likelyhood that we may produce
- inferior dogs. Inferior from the standpoint that they may not perform well
- at performing task A. This does not adress the argument as to whether or
- not the dog *should* perform task A or whether or not task A is important.
-
- This does tend support Chris' point. I do agree with Chris, to a degree.
- I am not quite as once-sided as Chris (not a flame!). I take the approach
- that while there is nothing wrong with producing "pet" quality dogs (that is,
- ones that may not perform task A very well), they should not be
- bred *unless* one wishes to specifically alter the breed, thereby creating
- a "new" breed of sorts. For example, in Britian, Guide Dogs for tthe Blind
- has a very large breeding program. They produce Golden-Lab crosses that
- are genetically selected for training as seeing-eye dogs. I see absolutely
- nothing wrong with this. I think that Chris might have a problem with this.
- Please feel free to correct me, Chris, if I am mistaken.
-
- I do remember that, a while back when this subject was discussed before, a lot of
- us agreed that for the working breeds, it would be nice to somehow fold in "field"
- work with conformation trials. That is, construct some sort of tests that evaluate
- each dog performing an appropriate tasks as well as the standard conformation tests.
- I think we all agree that each are important in their own ways. The problem is
- implementation.
-
- Sorry this got so long. I have not finished reading _The Dog's Mind_ yet, but
- thus far is is very interesting and well-written. Those interested might want
- to pick up a copy.
-
- Happy holidays everyone.
