line breeding and imbreeding...

Like Reuben said i double that , but the one thing that I haven't heard from anyone is the word cull. You have to be willing to cull very hard cause when you line breed you multiply all traits good and bad . So becareful what you breed make sure that the two dogs crossed don't posses the same bad traits and don't be lookin for a money train off of the pups , retain the litter and pick through it and cull hard on anything that doesn't meet the bar and friend set the bar high. All it takes is one off breeding and your yard could be ruined aswell as your good name .
