Phylogenetic reproduction refers to the fact that there are more than one ancestors in the four or five generations of the male and female bloodlines, and there is no duplicate of the same parent and three generations. This method is the systemic reproduction method.
It is a relatively light inbreeding. Many breeds of Russian Caucasian dogs have adopted this breeding method, because the systemic breeding of Caucasian dogs reduces the danger of inbreeding and can have the effect of inbreeding.
When using system breeding, you should know the bloodlines of the fifth and seventh generations of the male and female dogs in advance, which is an absolute reference value. (Note: Therefore, a good pedigree record system abroad has played a very good role in the breeding of Caucasian dogs. Domestic Caucasian enthusiasts and breeders should keep a record of the pedigree of breeding dogs.)
If the ancestors of the breeding dogs that are going to be paired, the same ancestor appears constantly, although they are not the same in algebra, they can also be used as a breeding tendency. In general, the proportion of excellent Caucasian dogs that are bred by using the systemic breeding method is also quite large, because when we breed, we can judge the genetic tendency of male and female dogs based on the records of pedigrees, and use them to make excellent ancestors. The characteristics will have a great chance to reproduce in the breeding Caucasian dog.
Female dogs give birth approximately once a year or every eight to eleven months.
Female dogs give birth to puppies in the wild in the autumn. Shepherds usually keep only male dogs and one or two female dogs. Kill the remaining bitches in a litter.
Only 20% of puppies can survive to adulthood because no one feeds them and takes care of them. Only the healthiest puppies can survive. In the Caucasus, there is no custom of selling dogs. So dogs are often given as gifts to friends by Caucasians.
Caucasians often keep puppies themselves because most dogs in the Caucasus cannot live to be very old. So alternative breeding is necessary. Some shepherds try to breed the best male dogs and others understand the pedigree of male dogs. (Image source: Visual China)
