As far as looking for your next breeding dog. What we would do is take the best super star that this pre potent dog produced when we out crossed him and then start slowly breeding this dog back into the family again and again as we got tighter and tighter we would be looking again for the Ole average Joe dog and as we got tighter and tighter we would be looking harder and harder .
Also you can take one this pre potent dogs brothers are sisters out cross him are her to a pre determined line of dogs take the best out of that liter and again slowly start breeding this are these dogs back into the family each time getting tighter and tighter again and again looking harder and harder as each breeding got tighter for the next pre potent male are female just the old average dog again . As you get tighter and tighter he are she will pop up sooner are later and you just have to go threw all the motions again to determined if he are she is the real deal pre potent stud are brood gyp you are looking for . Breeding is just a big circle is all it is . You need only one cross in there that works the more crosses you got in there the more head ache it will be for you .
this is basicly how I bred my dogs and rotated the females quickly and also the males at first to simulate many years of breeding...but I wanted to stay away from breeding depression which is what TexasHogDogs is talking about and some call it tired blood...I bred all kinds of dogs before the mtn cur but I didn't have a clue back then...just bred the best to the best or what was available...but we must have a clear goal in mind...and we must have the ability to pick the very best pups...Me personally I would never own a pre potent dog that acts and looks stupid...
one reason for sure is I don't have the room and I would't want to clean behind a dog that is only used for breeding when I can have a stud dog that does great in the breeding pen and in the woods...
There was a great mtn cur named gold nugget in the 1970's and 1980's and a few folks bred intensely to him...I knew a man who had a 7/8ths gold nugget male and he looked like a dog I would have taken to the pound...but that dog produced some sure enough bad to the bone hunting dogs when bred to the right females...but 3 male pups that made him famous were littermate brothers and I owned one for a while but a man kept offering me more money and a well bred female to boot of the same lines so I let him go...but the dam to the 3 males was one heck of a hunting dog and she did have gold nugget blood in her but not too much...those 3 pups were used to produce more kemmer dogs but the 7/8ths dog was given the credit and rightly so...
but there is one thing I know...sometimes when a very linebred and inbred dog is bred to a below average line of dogs there will be just as many culls as good dogs produced...but breeding within the family we can produce some litters of 100% hunting dogs where we have above average dogs consistently...but when the blood gets tired we start breeding sluggish dogs and the litter sizes get smaller and some of the dogs get smaller...and an outcross might work but usually will have a few culls and if too many culls scratch the plan and do it over with another line...but if someone already has a dog with 50% of your line that is already a proven hunting dog and that dog looks right then you just saved yourself a few years and that dog can be bred in to freshen the blood and keep you going for a good while before bringing in some new blood again...
but we can breed a few good dogs without having to get all serious about it if you don't want to spend the money...find a great hunting dog that has a good line behind him and buy several daughters from him as pups...but make sure the dam is of the same quality and the said dam has relations to the sires side of the bloodline...get the best female pup and breed her to her sire and now you will have a chance to get some top notch hunting dogs just that quick...I am hoping to do just that but the female is 11 years old and the male is a 4 year old dog that is burning up the woods...just trying to keep it simple...but like I always have said...breeding is half of it and selecting the right pups is the other half...and then proper handling brings out the best in them...
