Building a line of dogs

hell buddy after one generation they is just a cross off of so and so's dogs that would be just like crossing a walker to a blue tick first generation is just a walker and a blue tick cross . now after a few efforts at line breeding those pups for several generations you start getting a LINE of dogs to start inbreeding with to start to get uniformaty and then a LINE starts to develope . i'm sorry just takes several years to do it right and to truely be able to call it a LINE of dogs . but just my opinions on the matter if it just took one generation or even three [ sorry boys lol ] there would be more lines of dogs than the stars in the sky .
