"Inbreeding" refers to the mating of two dogs that are closely related or come from the same bloodline. Inbreeding of animals, such as cows and chickens, uses inbreeding to stabilize characteristics and make them a strong mainstream to expel bad characteristics, thereby achieving a genetic mainstream of ideal properties.

Some breeders practice a limited practice of what they call inbreeding. In fact, the mating methods of dogs with cousins, uncles with nieces, nephews with aunts, grandfathers with granddaughters, etc. are only limited internal mating methods.

The true inbreeding method is that brothers mate with sisters, father with daughter, son with mother, etc. Most breeders consider this to be true inbreeding. The dog mating methods of "father to daughter" and "son to mother" are called "reverse mating" in the inbreeding method.

For example: a breeder's female dog gave birth to a very good male dog, and he wanted to have more dogs of the same type, then he matched the male dog with his mother, and then gave birth to the puppies. Excellent female puppies are retained from the breeding, and then these female dogs are used to cross-mate their father dogs. The puppies born using this "reverse mating method" are very close to their father dogs. What's more worth mentioning is that the anti-matching method will not cause serious degradation.

The male dogs obtained by this cross-mating method are of great benefit to breeders. Because he can powerfully pass on all his advantages to the next generation. See how he looks like, that's what he will look like as a puppy in the future. Whether it is the systematic breeding method or the internal mating method, the purpose of breeders is to use time to strive for progress, and at the same time hope to reduce the risk of degeneration. Brother-sister mating is one of the most aggressive internal mating methods, and breeders can stabilize the dog's characteristics in a short period of time. But science shows that this mating method is fast but unstable, and the offspring of dogs show decline in health and energy.

Some research reports have pointed out that inbreeding will affect the deterioration of the energy of offspring, or the enhancement of certain genetic disadvantages, thus causing harm to the dog breed. But as these negative traits grow, other advantageous traits will also be genetically enhanced.

In fact, the most important thing is that the genetic factors in this "blood clan" match each other and use the principles of eugenics to retain the excellent qualities and drive out the bad qualities. This can be said to be successful.

There is also a common saying that inbreeding can easily produce dogs with deformities or defects. But it turns out that the inbreeding method has no correlation with the aircraft model. In fact, during the in-breeding and mating of dogs, the next generation of the dog is just allowed to reveal everything it has. It is just bringing everything the dog has, including its potential, to the surface. Sometimes, there will be some abnormal dogs or stillbirths, which just means that your breeding group itself contains this characteristic.levy.

Another positive feature is that the degenerative nature of inbreeding can be completely eliminated by mating a degenerate female dog with an excellent, unrelated male dog. This mating method is called "external mating". When an inbred female dog undergoes outbreeding, all her weak mainstream characteristics will be completely swallowed up by the strong mainstream characteristics of another excellent foreign breeder, leaving only the advantages, and the puppies born at the same time will Dogs should be healthy and strong.
