some of the studies you will see is hundrreds of years of genetic interpitations ...thats not gonna effect what we do in short term ....most people will be lucky to breed 5 generations of dogs in there lifetime ... most of us start our breeding programs years after we start hunting ...
Larry...I agree with what you are saying...we can breed 3 generations in 20 years or turn them over fast and get 7 generations...for me, my logic was to keep second and third generation males for hunting and breeding but mainly the third generation male...line breeding and inbreeding him...kept quite a few males off of him and hunted them...I felt like I could use these pups/dogs for hunting and breeding when needed...but the females I sometimes bred on the first heat if I knew they were what I was breeding for and I turned them over quickly to move ahead with the line as well as in purifying the strain...I did this project for me and it worked out great...once I felt like I was where I needed to be I slowed it way down...
But here is anorher way of looking at it...the majority of the dogs I started with were purebred mt cur with one bmc at the beginning for size and quieter mouth...the mt curs were already top bred hunting dogs of many generations prior...I also had a Texas Smoke mt cur bitch that was out of Texas Smoke and out of one of his daughters...I planned that strategy because of his greatness...but those were already an established line of dogs...I just picked up and moved it further but in the direction for hog dogs and not tree dogs. In my mind there is no reason why someone needs to start with junk when they can do the homework and start with a good line of hog dogs...
