well i was once told all blood lines suck or all blood lines can produce good dogs i think when we talk scatter bred and line bred most dont even no what that means line bred is on a single dog or a single family related to a few special related dogs any way i run my own line now of about 4 different lines and used family related dogs now i am just getting it down and have many years of proving grounds to go but i have a good group guys helping me with my line as well anyway these dogs are all related some were usually i would focus on what ever dogs u like and make your own path with out reinventing the wheel so to speak alot good dogs might be looked at as scater bred but are actually line bred on certain good dogs or dog that the individual breeding the dogs up might find he liked or is working for them some my best ogs were 3 way crosses or 4 way but that dont mean nothing u have to go threw every breeding with a strict culling process involved that doesnt mean u have to put own all those that dont make it just make sure u dont breed it or let some one else now these are just the way i deem things breedings alot luck do what u can to have the best odds like poker
