You are referring to line-breeding which is acceptable. Just keep in mind that this is done to "enhance" good qualities, temperments etc. but it can also enhance the bad qualities of a dog. Usually used when a ch.male is line bred with a ch. family member. I would not line breed just for the heck of it. There are certain rules like its ok to breed up and down the line but not brothers and sisters etc. Im not an expert on this because I dont practice it but you can find plenty of info online.
"You are referring to line-breeding which is acceptable"
This is not linebreeding its "inbreeding" and should only be attempted by a breeder with many many years of experience and one who has studied the genes and health issues of their line. This is not something that a novice should attempt.
Inbreeding close relatives father-daughter, Mother-son,etc gives you a higher chance that you will have puppies with genetic disease. Are both parents OFA,CERF? What if you are doubling on something like PRA or Cataracts? with a good gene pool of stud dogs available I see no reason to do such close breedings unless you are willing to keep these puppies for a year or more to monitor their health.
doxielover1, ok so it's called line-breeding & ok to do this. I bred my 2 dogs for the first time & the mother needed a c-section & the vet told me not to breed her anymore, so that's why I was wondering about the FATHER & DAUGHTER breeding. but now BEAGLES is saying it's not ok.
I know a couple of breeders who have produced champions in this way. And there are I am sure hundreds of others have as well. I probably would have been to scared to try it if it hadn't been for one of the breeders I had talked to. And maybe I shouldn't have attempted it so soon, but after more experience with breeding I may try again, but ONLY with tested dogs.
It can be done, but should only be done by experienced breeders who know their bloodlines in and out. You can enhance great qualities, but can also enhance terrible health and gentic isues if your not educated on the lines. It should only be done for specific reasons, never simply 'out of convenience' .
It can be referred to as both linebreeding and inbreeding - technically speaking, linebreeding is a form of inbreeding. The big difference is that "linebreeding" is officially called that when you are doing the close relative breeding with a goal and when you are trying to draw out a trait that you know is established in the dog who is the closest common ancestor.
I do a little linebreeding myself - not as close as what you're talking about doing (I have a 1/2 aunt that I breed to a 1/2 nephew - the common ancestor is a gorgeous dog with a very sound healthy, bloodline).
When you know what you're doing and what you're linebreeding on, linebreeding is actually safer than outcrossing (breeding 2 unrelated dogs) because you are working with both good attributes and faults in a controlled manner and concentrating them slowly. The closer the relatives are, the faster you concentrate them and obviously you will see more results in both the positive and negative areas. I really prefer my linebred litters - especially when I'm hoping to concentrate a specific trait so that when I use that pup to outcross with his/her traits are defined and I can focus on correcting any flaws he/she may have by using them with a dog that compliments them.
I would ONLY consider what you're looking at doing if you have a very good understanding of the genetic health in the line. OFA & CERF testing is nice, but tested dogs can still produce defective puppies. It's more important that you research the background of the family tree and find out if there are any known occurances of ANY defects. If you got your dogs from a BYB or PuppyMill that can't give you any insight into what their dogs have produced or what is in their lines I wouldn't even consider doing it. If the dogs come from a good healthy line, and you can research the background far enough that you're comfortable with what is in their history, you can consider trying it.
