Like to like mating implies the best to the best and the worst to the worst where the worst is not used at all. For most breeders, like to like matings are between dogs which resemble each other greatly and so similar type dogs are bred. These dogs may or may not be closely related. The pups resemble their parents because of the genes in common with them. If those parents resembled each other their progeny would be even more like their parents. This tends to make the population look more uniform, however there is little increase in prepotency from this technique.

The system is basically simple but the breeder must identify faults and virtues and it requires breed knowledge. The pedigrees of both dogs should be examined carfully to try to identify the ways in which the dogs differ and what the expected outcomes could
