What principles should be paid attention to in the selection of dogs

The selection of dogs is to choose the right male and female breeds, that is, how to choose the right mate for male and female dogs. The principles are as follows:

The main results are as follows: (1) choose male and female dogs with common advantages to mate, so that their advantages can be maintained, consolidated and developed in their offspring.

(2) male and female dogs with common shortcomings can not mate, if mating, it will make the shortcomings of both sides more consolidated.

(3) in the case of lack of good breed dogs, we can choose a dog with a certain advantage to mate with another dog with relative disadvantages, and use the advantages to overcome the disadvantages. However, it should be noted that the convex back can not be used to transform the concave back, and the "X" limb potential can not be used to correct the "O" limb potential.

(4) in the optional age, the most ideal is to match the strong age with the strong age, or the old age (female dog) with the strong age (male dog), to avoid the old age with the old age as far as possible. Dogs over 5 years old that have never been bred before (virgin dogs) are not suitable for mating.

(5) when selecting and matching, attention should be paid to the proper size of male and female dogs so as to avoid injury. Inbreeding (within three generations) is strictly prohibited except for special needs.
