Well that is a very hard question to answer it really really is. I know people that have done this maybe not with a particular gyp but I have know men that have bred four gens deep and have great great dogs threw out all of this . Then they get a wild hair and they go off and breed to this super bred stud that was really not proven proven just thought are hear say to be proven know what I mean . They are so wound up in the dogs great ped that they took the chance and five six years later are cleaning out their yards ! This is after they have done bred the bad gene pool threw out there yard making crosses and also family breedings. You do family breedings of this type your are threw it may not be till two years later are three but you can bet yo sweet tussy you are done !
Here's the kicker on all of this .
Yes you can breed to this dog to your proven great bred bitch and sure you are going to get some super dogs some great dogs you might not even have a cull in that first breeding . But here's the catch . You had all these good dogs in that liter so man you are on top of the world so then you breed some of these dogs across your yard well now again you might have a high percentage liter , then you breed those dogs and what happens





All the sudden out of no were !!!!!!!!!!!!!!!!!!!!!!!!!! You Percentages drop boom ten pups 6 culls 4 half ass dogs. You are saying wow must not have clicked this time . Then you are breeding to some more stuff from this dogs brother boom ten pups 8 culls 2 half ass dogs. All across the yard anything and everything with this Super Culls gene pool in there is now starting to react . Now you are saying what the hell and scratching your ass so you try another breeding with some more of this stuff that Super cull is in and bam man ten pups ten culls.
The deal is each time your bred those dogs with that Super Cull in there even tho you were having some good dogs at first those bad genes were double tripling and so on and so fourth now all the sudden this bad gene pool has over ridden the good genes from your good dogs and man o man one Super bred Cull screw up four gens of dogs .
How hard would this be to re coupe?

??
Almost impossible !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Haul you some dirt in there cause you ain't got nuff !
x2...you can breed down or breed up. breeding up is only breeding top of the line males and females of a related family of dogs. the big mistake is outcrossing to an unfamiliar line of dogs. Once the line is bred tight and you bring in a super duper stud that is a 1/4 cat, 1/4 bmc with 1/2 redbone and cross it into your tight line of cur dogs then you just brought in a bunch of trash and you might get a once in a lifetime dog that can't reproduce himself... and the rest of the pups are culls...I reckon that is why we have so many culls.
like Texashogdog said earlier...it is the little things that we should look at...a dog man spends days, months, and sometimes years deciding who to breed too and why. And then critique the hell out of the litter of pups...
If color was a hunting trait everyone would have a good hunting dog...
having said all of that...when you have a long line of nothing but yellow dogs and you cross in an unknown dog that hunts well and he is a brindle dog then how many brindle pups will you have when you cross this dog with the yellow dogs??? could be 4 or could be 10 brindle pups and probable other colors and a few yellow ones...that is the way I see hunting traits but they are not visible...studying the pups and testing in the woods will tell you...but I look at the little things and after a while you can see tell tell signs in a pup if you know your line of dogs...but nothing is a 100% until you see it in the woods.
here is some good logic. a king in the old days told his son...if you want your sons to be brave warriors and leaders and your daughters to be beautiful then find a bride that her brothers are great leaders and warriors and the women to be beautiful...marry even if she is only fair...because she will give you what you want...but do not marry a beatiful girl from a long line of inadequate warriors and women who are on fair at best... I am not good at quoting but you get what I am saying...
same thing with dogs...if you don't have a good female but one that comes from a very good line of dogs you breed her once and replace her with a great daughter, cull and cull very hard...breed the next generation and do the same...to me it is better this way than having to long across the land for another prospect. If she is not a good hunting dog but her line produces good to great dogs then she is worthy for one breeding because she should be bred back into her line...
but like i am saying... breed the well bred gyp once and move her on...the idea is to remove the bad genes as often as possible...
the more bad genes that are replaced by good genes, greatly reduces the odds of getting sorry pups...but we must be honest with ourselves and we must take off the rose colored glasses. and call it like it really is...
one bad cross and it goes south. once your line is established you never bring in a 1/2 this or that into your line...if you want to bring in some pit then breed the cur dog with the most grit to a female pit that is slender and leggy with a good handle and then breed the offspring again to a gritty cur(related) with a 1/2 pit/cur pup that looks and hunts right. when down to a quarter pit then cross that one back to the line of dogs but one must cull hard at the beginning because the trash will be there...the idea is to retain the good and discard the bad genes...I would feel comfortable with calling the pups that carry 1/8 pit part of the line and breed them as part of the family...but the qualities that one wanted originally from the pit must be captured into the line of dogs or what would have been the point to go through the truoble...
this is not in the books just my personal opinions and how I have done it in the past but using bmc into the line of mtn curs I had for many years. I did it to gain size and quiet them some on track...
Thats what I like Rueben the real deal , the real hands on you cant beat it . Books are great guide lines and teach great things but they will never replace n the flesh experince like a sergun who you gonna let do the surgery the one that just got out of college are the ole sergen that has done it a 1000 times.
