Line Breeding?

Question

Do any of you line breed when you breed or do you cross out each time? I was wondering because I have heard good and bad about both, and with healthy lines it is better to line breed to an extent, How close in pedigrees do you get though without causing problems? I am talking about breeders who do health testing and such for the betterment of the breed..

What if it is a female bred to a male, they share same father different mother, not out of same little of course would that be line breeding or in breeding?

Answer 1

Really, for a quality breeding program, you need to line breed to some extent. Otherwise, with an outcross, you really do not know what you are going to get.
Of course, health testing must be done weather you line breed or outcross. It is just bad breeding to not do the health clearances.
The extent to wich you line breed depends on many factors, and can then cross into inbreeding, which can also be useful when done by someone who knows what they are doing. If you go through outcrossing all the time, you are not producing a consistant "type" and therefore are just producing puppies hoping something good comes along, but even then, it rarely will produce another like it. Line breeding is used so the type can be better predicted and changed if desired.

I have done the exact breeding you have stated with FAB results. 6 puppies, 5 champions, all OFA cleared for everything. If you what you are doing, it is great. If Joe Blow just took two dogs that share the same father, different mom, different litter and bred them, it may just be another backyard bred bunch of crap. It is the dogs that MAKE UP the 2 you are planning on breeding. If there is QUALITY BEHIND them, then it would be good to attempt. If not, why bother. The half siblings that you are planning on breeding should be of exceptional quality!!!!!!!!!!!

Answer 2

I breed Rhodesian Ridgebacks & I prefer to line breed with careful research into the genetics of the dam & sire.

The optimal line-breeding combination will help assure a greater chance of the genes (both dominant & recessive) 'hooking up' to produce those qualities in the puppies.

Line breeding should only be done when you can trace both parents back at least 4 generations & are aware of what their parents, grandparents, etc have produced. Know about their siblings and what they have produced as well. This gives you knowledge about what runs in your lines, & what has occurred in other lines that have been crossed with yours.

Documnetation of negative traits (such as hip dysplasia) should be investigated to see if it is on your side or another breeders lines. This involves contacting other breeders of the crossed dog to get information on their pedigree & traits.

The benefits of line breeding are that the positive traits are more likely to show up in the puppies, due to the closeness of the sire & dam. The downsides, of course, are that negative traits have just as much likelyhood of showing up, so it is important to research & see what you are working with before proceeding.

Outcrossing (most commonly associated with mixed breeds, but also by going very far outside of your bloodlines in your own breed) is just as risky, even more so for a knowledgeable breeder, because ANY genes could potentially cross & show up as positive or negative traits in the puppies.

I have heard that the optimal relationship for linebreeding is uncle to niece. This results in the sharing of a father/mother on one parent with the grandfather/grandmother of the other parent. The litter I have right now is the result of such a breeding, & all puppies have strong resemblance to their parents.

Answer 3

Line breeding can be very beneficial to the breed when done by an experienced breeder.
Line breeding can emphasize strengths, making them concrete in the line.

Be careful though, there is a fine line between line breeding and in-breeding.

Never, EVER breed any dog with it's offspring or littermate.
Good line breeding may involve breeding a female with, say, her sire's littermate's offspring, or breeding a male with his dam's littermate, but that is the closest you should get, and don't repeat such close breeding much.

Line breeding can also emphasize faults, and you do not want a serious fault set in stone in your line.

I never do line breeding more than twice in a row, and only if both dogs are SUPERIOR examples of the breed standard.
One of my main methods is to breed with a dog that has two or three of the same dogs in his/her 6th or 7th generation pedigree, but not related any closer than that. That gives you the same building blocks, without the risk of breeding too closely together.

Answer 4

We do quite a bit of line breeding. When we do an outcross that pup will then be bred back into the line. That way we will know if we achieved what we wanted from the outcross. The point is that every breeding is done with a goal in mind. Just breeding for a batch of puppy's equals a waisted opertunity.

Answer 5

I have line bred. I breed on lines that I know will be an asset to the breed. I won't do half sibling breedings. But say, I have a breeding (Ryker x China) and I kept Oliver. I am planning on breeding China to Desmond and keeping back a dog. I am planning on breeding Sushi to Oliver and keeping back a dog. This would be a line breeding on China if I bred the 2 pups that I kept together.

This would be a line breeding on China. I left out the CH titles, OFA's, ect... and shortened the names,so it would be easier just to look at the names on it. What you gave as an example would most likely be considered linebred to most (1/2 sibling breedings) I would think it is too close for comfort. The breeding that I gave an example of shows a line breeding on China, but with outcrosses on both top and bottom of the pedigree. It would hopefully produce some nice type, movement and angulation in our breed for the show ring.
