Putting my neck on line-breeding

I'm quite interested in the subject too and usually takes any chance I get to talk about it.

I probably didn't put that very well. When I said that it isn't likely with a 50 - 50% outcome I was thinking e.g. of the people thinking that if you breed a bitch that is 60 cm's high with a dog that is 20 cm's high, most of the puppies will become 40 cm's high or those who simply think that puppies always and regardless inherits 50% from each parent.



Maybe some do inherit 50% from each parent but some maybe inherits 45 - 55%? If one gene is dominant over another gene, your puppy might have inherited both genes but only the dominant maybe shows itself. Let's say that an owner have a black bitch with one A (black) gene and one B (brown) gene but A is dominant over B so the bitch is black and the owner doesn't know their bitch have the B gene.

They then decide to mate their bitch with a brown dog that has two B genes and expects to get 50% black (A gene) puppies and 50% brown (B gene) puppies. In the big doggy genes lottery that maybe happens now and then but it is not the most likely outcome.


Some people actually doesn't think/knows about that their dogs/bitches can carry genes that they can't see the result of, in front of their own eyes. If their mongrel doesn't hunt and have never wanted to hunt, they do believe that their dog/bitch can not carry any hunting gene from their e.g. Foxhound grandfather.



Then we have things like HD, that has polygene inheritance + it can be affected by environmental things like over feeding, to much or to little exercise etc.

Only the fact that it is polygene inherited makes it complicated, with not only one or two genes involved in deciding if the dog should get good hips or not, without several genes. If one of those genes is "damaged" maybe the dog will get a bad HD result but if the other genes are "undamaged" maybe the dog will get a good HD result though not all the genes involved being "undamaged".

Here we really can talk about that even if you only breed on dogs and bitches with ideal HD results, you still can't guarantee 100% HD free offspring and it might not even be the breeders fault if the buyer e.g. over feeds their puppy.






As you say it can be difficult to define what characterise a good working dog and what I think/wants might not be what anybody else think/wants. The same with what you maybe see as irrelevant, I maybe see as relevant to maintain the breed characteristic or something desirable to make the breed more suitable for its purpose (and to that I would never count things like e.g. peke-faced Persian cats, to mention what first turned up in my head as an example of what I don't like).


I don't believe in mass-producing puppies to get one that might meet so and so criteria, I believe in breeding with a goal beyond this generation and if you don't have to achieve everything in one generation, you can let things take some time. I don't think only champion purebreds should be allowed to breed and though I have only bred one litter, I hope to breed a champion myself one day but I don't believe it has to happen in this generation.

Besides I think maybe Sweden is a little bit to small (about 9,3 million Swedes in total, I believe I've heard that in London alone, there is like 15 million people during daytime?) for it to be possible to sell huge amounts of mass-produced puppies.

CC-I'm am seriously finding this eye opening!! I love the GSD hip scoring in particular <font color="purple">as I often saw pups advertised as Hip Scored</font> but never really understood what they were going on about!!
Breeding really is a proper science! I think that's why I get a bit annoyed at Back Yard Breeders who are out for a quick buck sometimes at the expense of the poor animals.

Just to clarify *wonders why CaveCanem didn't notice this*, puppies can not be hip scored!

If a puppy is in an accident you can x-ray its hips and puppies can have parents that are hip scored but hips are never scored until after 1 years of age. So obviously those who advertised, didn't know what they were going on about either.

Very interesting stuff! Thank you both CC and FL!

Sounds like the German GSD breeding programme is very specific and targeted and I can see the point of that.

I suppose my only thought is that this is not a breed - mongrel debate but a responsible - irresponsible breeding debate. Some UK pedigree breeders breed irresponsibly, often on purpose (I also don't like the Persian cats) and according to an arbitrary standard of 'beauty' while sacrificying health and temperament which I think is a mistake.

I suppose the problem with a mogrel is the lack of history, but in theory a breeder could focus on inter-breeding and after a few generations they would have collected quite a bit of information on the dogs' history even though they were cross-breeds.

It also seems that anyone cross-breeding two well known pedigree dogs could satisfy all the requirements set above, i.e. have information about past generations from which they can gleem genetic info, carry out all health checks on parents, breed with a specific purpose in mind, etc. That would suggest that there is nothing wrong with Labradoodles, etc. as such, rather with the way some people choose to breed them, but that is true of anyone breeding anything.
 
Good points

What I could have said to keep things short in my post last night (sorry, beery
tongue.gif
) was that if I wanted a working type I would go to a kennel, say, Vongraf or Latchets or Karthago or Dollenweise, or if I wanted a showline that I might work I would go for Arlett or Silkenwood or Optikas or Mayenser.
It is that specific!

Well some of the hardline peeps in Germany are wanting to bring in Mali blood for a few generations but my concern is, what on earth will happen in the in-between generations.
Malis are now the dog of choice for a lot of European police forces as they are so much harder, like machines (I wouldn't fall out with one) for example, one I am familiar with has started biting the arm WITHOUT the sleeve because he has worked out the routine and the arm without the sleeve is so much more fun

The showling German Shepherd is now a mish-mash of blood from all over Europe, indeed the Sieger this year and last was a total wildcard from French lines with no linebreeding in six generations and his daughter was the Siegerin - the 'fathers' of the breed look at breeding as well to determine which dogs should be promoted in a particular year to address faults which crop up.
Even the working lines are more from East German, Czech, Belgian and Dutch lines.

A lot of people will tell you the Czech and DDR dogs should be classified as a different breed

Well I missed all this one too, CC I think you should put yourself forward as PR of the new fb group
smile.gif

Ref the czech working lines, I oftenwonder if they have mali in there already as they are so different from the GSD as I know it.
 
That has been rumoured, MM

My mate imported a working 'Malinois' and he is quite content that there is any and every breed in there

I wouldn't like to muscle in, and I think three PR roles would be a bit greedy

and there are only so many meetings with so many groups I can take

You have good points too Booboos.


I think Patches started the thread because she wondered why today's mongrel and cross breed puppies sometimes cost as much or more than purebred puppies. (To which my shortened answer is that I think that is wrong.) But the thread quickly evolved away from the price tag question and into a what to breed and why debate?




I certainly don't believe that breeding purebred dogs are a guarantee for that you're a responsible breeder, far from that and when I've talked about breeding my own dogs, I think I have always mentioned that what is first and last most important for me, is the temperament, in-between that comes health and looks.

What would be/is the point in breeding champions with perfect health, if they have a temperament that makes them impossible to live with.


I would never sacrifice neither temperament, health or looks but I would make compromises about the looks (I don't think only show champions are worthy of breeding but it must still look good enough, compared to the breed standard), the health (e.g. I would not only consider dogs with A hips but dogs with B and C hips too, if other things "speaks" for those dogs) and maybe the temperament (how does so and so temperament thing affect how the dog is to live with).





I agree that someone who is e.g. crossing two breeds can satisfy all the requirements set above, the problem is that they rarely do it. Since you mentioned Labradoodle, let's take them as an example.



The Australian Labradoodle, the people breeding them are aiming to make it a purebred breed. In the beginning one of the parents was a Standard Poodle and the other was a Labrador Retriever, the first generation offspring was then perhaps bred back to a Standard Poodle and the second generation offspring was perhaps bred to another Labradoodle etc. So if you buy an Australian Labradoodle, it can have several generations of Labradoodles in their pedigree.

Australian Labradoodles can have HD, PRA, Von Willebrand, Elbow and patella disorders. I'm not saying anything about the HD because it is a jungle with its polygenes etc. but e.g. both Standard Poodles and Labrador Retrievers can carry genes for an inherited eye disease, PRA.
Australian Labradoodle was created 1989, according to Wikipedia, and I know that at least 1990 (that is when I got my first dog) specialized vets could do a visual eye test. It doesn't detect if the dog is only a carrier of a PRA gene but it can detect if the dog have developed PRA or have signs of developing it.
If the dog gets it before they are old, it is more likely that they have an inherited PRA but when dogs are old, they can develop PRA whether they carry any PRA gene <u>or not</u>!

Now I would think that a responsible breeder with such a plan of creating a new breed, knowing that both breeds involved can carry inherited PRA, would only have bred dogs who hadn't only been eye tested themselves, without also had parents and grandparents that had been eye tested, preferably way up until old age.
Surely that would have made it less likely for any of of those PRA genes to slip through the cracks and end up in "my" new breed?


E.g. Von Willebrands is a blood coagulation abnormality that Standard Poodles can inherit. Admittedly I don't know how common it is in the breed and I don't know how big risk there is that you happen to choose a Standard Poodle carrying the gene for the disease, when you choose the dog/dogs and bitch/bitches to use in your cross breeding.
But regardless of if the risk is small or big, the fact is that it did also slip through the cracks and ended up in this potentially new breed.




Then we have the "simple" Labradoodle, one parent is Standard Poodle and the other is Labrador Retriever, a cross that can be done by anybody owning an intact dog/bitch of either breed.
Personally I admittedly don't think that many of those who breed these Labradoodles only uses parents that e.g. have good HD and elbow results and have been eye tested etc.



Not all inherited PRA in dogs are caused by the same genes but today e.g. Standard Poodles, Labrador Retrievers, Australian Labradoodles, Labradoodles and Finnish Lapphunds are amongst those who can have a gene test to check if the dog/bitch carries their type of inherited PRA genes. It is one of those things where you do inherit one gene (chromosome?) from your father and one gene from your mother (
tongue.gif
50 - 50%).

There is three possible results :
Non-carrier, the dog have inherited two PRA free genes and can never produce an affected offspring.
Carrier, the dog have inherited one PRA free and one PRA affected gene.
Affected, the dog have inherited two PRA affected genes.

This far "my" breed club only recommends that breeding animals are tested and to not risk minimizing the gene pool too much (which could lead to other diseases, problems etc), they also recommend breeding both non-carrier + non-carrier and carrier + non-carrier (at "worst" you will still only get carriers that can not develop the inherited PRA).
I have no doubt about that if they (breed club and SKK) feel that only recommending doesn't get the desired result, it will change from recommendation to mandatory.

You make some valid points Finny. When I had Buffys hips x rayed and my vet predicted a score in the 30s (he was right she was 38
frown.gif
), I was very upset as she was the last of my line. He said to me that whilst he knew I would not breed from her, in some ways he would rather see a bitch with her temperament but poor hips bred from than something with good hips but bad temperament. Going on the fact that the dogs I have known with bad hips have always had fairly long lives and given a great deal of pleasure, something a dog with a bad temperament can not do to the same degree imo, I do see his point. Breeders do have to look at the whole dog and not just breed for one thing to the detriment of the rest of the dog.

Ouch!


I can see why he thinks the arm without the sleeve is much more fun but I'm glad I'm not a figurant (that is what they're called over here) with that dog...
