Beginners guide to line breeding

[davidcavill]

With a breed that is genetically healthy and have a conformation which is not extreme there would not normally be a problem

[davidcavill]

It all depends on the genetic health of the parents. Like people to unhealthy course on more likely to produce unhealthy youngsters were asked to fit and healthy animals are likely to produce puppies which are themselves healthy and will live long lives. Just being a half sibling is a relatively minor factor but something you do have to take into account when you are reading animals from the same gene pool - as you are with pedigree dogs.

[postmortem57]

what are the odds of having an ill puppy if they're half-siblings?

[MrMisanthrope1]

if you want to see inbreeding like youve never seen before study the gamebred pitbull terriers pedigree. the real performance bred ones.

Nothing wrong with boring if what yiou are saying is important - they are not synonymns

[candidomoreno666]

you are too boring

[candidomoreno666]

@MrMisanthrope1 what are you saying is this english

[judlively]

Is the logic behind all this sounding stupid to anyone else?

[davidcavill]

What you say is not wrong but it does not tell the whole story. Well managed and thoughtful selective breeding has provided us with more meat, and more eggs, milk and wool than nature could ever provide. It has also resulted, generally, in excellent, healthy pedigree dogs . There are problems it is true - but it is selective breeding which will solve them

Do no condemn out of hand - it betrays narrow mindedness

[LionessCub1]

I believe the real problem here is not simply inbreeding but that we are allowing people to decide, which dogs to inbreed. People who are easily swayed with motives that don't reflect the well being of the poor dog. Motives like are my dogs legs short enough to fall into the standard of words written in a book over 100 years ago. No care that they are breeding out the ability to swim run normally breathe properly or even do the job they were originally bred to do. It's quite sad

Wolves do not inbreed. It is not "Natural" as you would assume since "dogs" are a part of the wolf family. Only "alpha" individuals pair, and breed; the off-spring venture forth to find their own partner (wolves mate with one for LIFE, if one dies sometimes a new mate is found).

Inbreeding causes good genes and bad genes to to double up, thus INCREASING the changes of diseases. Diversity in breeding ensures a better chance for mother nature to "improve" the gene pool, or health of the creature.

[davidcavill]

And there are taboos about close inbreeding in most human societies (although cousin to cousin over several generation is not uncommon) but these are totally ignored in the animal kingdom- by the animals!

[davidcavill]

Dogs do not die of inbreeding. In fact, very few dogs have conditions brought about by inbreeding from which they die. This is not to suggest that having a dog which is ill or disabled is not heartbreaking or that there is not a problem with irresponsible selective breeding - there is. However, by definition, dogs with a genetic disease will probably not be from responsible breeders.

[shallyjean]

Imagine the poor dogs talking to each other-> "Hello uncle- cousin, brother -dad! Where did mom- sister-aunty-cousin go bury Grandma-aunty's dog bone?"

Human beings do not practice in-breeding, why on earth do we do this to our pets, causing illnesses and birth defects to "perfect" an image of something that would not naturally occur often in nature? I have read many heart-wrenching stories of owners' buying a pure-bred and then watching it die because of too much-inbreeding.

[davidcavill]

I think that what you say has been true - certainly until ten years ago - but things are changing fast. You only have to see the improvement in Chows to realise how quickly these problems can be resolved given the will. Rome and day come to mind. Why is it that so many people demand and instant solution and, if they cannot get think that banning it is the only answer - patience is the virtue we need here - and understanding

[entfy]

The only problem with the inbreeding coefficient is that with each passing generation as the gene pool narrows, the coefficient is exponentially increased. Basic biology teaches us this. We can look to the Royal lines of Europe and their health problems, most notably researched is hemophelia. While you might achieve some results that are better, you also increase those negative faults. Your geneticist while in good standing with the KC is CONT...

[entfy]

not in agreement with many other geneticists studying breeds and their standards. Many US geneticists differ in their opinions for the KC and argue that more insurances towards widening the genetic pool voice their arguements to deaf ears of the show community.
