Consanguinity
All the dogs of pure race had consanguinity in the beginnings to create each race in individual. The crossings between consanguíneos are often necessary to give continuity and to increase certain characteristics (virtues) within a line of blood.
The consanguíneo crossing (innbreeding) is the crossing of parents with children or between brothers.
The crossing in line, is the crossing between unit with a kinship furthermost.
In pedigree the consanguinity degree can be seen, between members of the same line of blood or other lines.
The problem of the consanguinity is that in addition to the virtues also the defects are duplicated (tares) and is for that reason that the criador that work with consanguinity in their raising, will have to very thoroughly know its lines of blood.
