Line breeding

[@NeuKrofta]

Its how herds have been bred for thousands of years until very recently

I wouldn't do this to any animal. This is why a lot of purebreds have lots of health problems. If you are breeding a certain breed. Get it from another breeder. Look at that family tree. Breed for health and function rather than looks.

You are using human ideas of incest and applying it to animals. When we SELECT for vigor and fertility, as well as for other attributes, there will be less talk about the evils of inbreeding. In the meantime we shall hear about it mostly where vitality and fertility were low in the stock inbred upon. Because both of these are requisites - one to insure life and the other for reproduction-they should be possessed in a high degree by the dogs one intends to inbreed upon. If no other animals are related, but one animal is related on both sides, we breed in-line to that animal. All the "pulls' are in the right direction and we double up allele pairs that we like!

Let's get the facts straight. Inbreeding doesn't in itself cause disease, it exposes disease. 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. (in fact, in lab mice, or guinea pigs, they are heavily inbred for as much as 26 generations, and are nearly identical clones of each other) ok guys get you facts straight.... line breeding that is monitored and controlled by experienced people can be a very good thing and doesn't harm any offspring in fact.... when researched... in our breed, the lines that were line bred were actually "cleaner lines" with less health problems.... done badly line breeding can be a disaster but done well it can be beneficial ...

​@@VonGontaHaus exactly it exposes bad genes and if they are culled from the herd it removes it from the bloodline. Linebreeding in this way also creates diversity. It's a matter of proper attention and doing it right and controlled.
