There are many formulas for line breeding and these are discuss in many good books on dog breeding, there are differnt degree’s of line breeding as well. So it is not my attenion to go inot all these formulas here. However two which have proven very sucessufl to me over the years are when you breed a grand dauther to her dams sire, (i.e. grandsire) this does require some advanced planning and does require both dogs to be of very high quality with all the good traits you want and within there breeds standard. Half borther and half sister breeding with a out cross line in the middle of there pedigree has also proven very good results if the dogs used are of very good quality, sound and have great temperments. Line breeding does require knowledge and research.
