Line breeding is the most commonly used breeding program, as it retains true virtues of a line, but it also introduces new blood.
The only way to set type on a good dog is to linebreed.
Outcrossing only brings in so many other problems that you will never find
them and never breed true to type.
INBREEDING AND LINE-BREEDING
Inbreeding consists of the inter-mating of relatives, and it is virtually impossible to breed pedigree stock of any kind without having some
relationship somewhere . Once a breed is established, it is impossible to breed a male and female within this breed without finding some ancestors in common. It may be so far back that you can't trace them, but by inbreeding these common ancestors, your breed was formed.
Most breeders consider "outcrossing" as breeding stock who are completely unrelated in the last six generations. This is as far as most breeders trace their stocks' ancestry, unless they have personally linebred for a longer period of time.
"Line-breeding" is considered to be merely a mild or less intense form of inbreeding. Mating of distant cousins, or mating dogs who come from
the same kennel and same strain but who have no common ancestors closer than four or five generations behind them.
