One name appearing several times in a pedigree?

[Bix]

Further to my recent post I am tentatively looking for a good breeder .

I've found one I like the look of, but looking at the pedigree of one of her stud dogs, there's one particular dog that shows up several times going back through the ancestors. Surely that can't be a good thing?

This is all new to me so not sure how common that might be?

Perhaps if you could tell us what breed you are looking for someone with knowledge of the breed could point you in the right direction.

As for the same dog coming up in one dogs pedigree that would be a red flag to me.

Check the breeding co-efficient of the dogs in question here: http://www.the-kennel-club.org.uk/services/public/mateselect/inbreed/Default.aspx

Talk to the breeder and others in the breed re that particular dog. It depends whether your breed is a low numerical one or not as to what is acceptable; sometimes in the rarer breeds with few litters registered you have to accept what might otherwise be a high co-efficient.

Line breeding can bring out the best and the worst in any breed,it depends so much on how healthy and sane the dog line bred to (that is the one appearing several times in the pedigree) actually is.You can find out the Breeding Co-efficent via the Kennel Club, we breeders do line breed to set a kennel type(look) and temperament.It is`nt all bad! For instance our own European Royal Family are lightly line bred..notice in the Family the same teeth/nose in almost all of them,each are typical of their breeding!! Sorry,we breeders see people in the same light,it is called stockmanship!!
By the same token ,if you want to acquire a look/type of another line in your dogs..then buy an in-bred one from it,it cannot fail to reproduce that type in even the most motley bitch.

I'm looking for a cavalier and the dog that keeps cropping up is a Leelyn dog which by all accounts are good quality (sorry don't know the correct terminology). The closest it gets to the stud dog is as a great grandparent on 2 sides (the grandparent on his dad's side is the cousin of the grandparent on his mums side - so they would be the great grandparents of my potential new puppy) (keepin up?). He then appears a couple more times further back but my head started to hurt trying to work out relationships by that stage lol.

I will have a look at the co-efficient thing, thank you

It depends where the name comes up. strategic and careful Line breeding is perfectly acceptable imo, I would check the breeding co-efficient as suggested above. it's a brilliant tool.

Okay she has 2 litters due this month to 2 different sires. One of those sires comes up as 1.1% against a breed average of 5.2%, the other sire, with the relative that's common in his pedigree comes up at 21.6%! I'm guessing that's bad! But the other litter could be a winner.
Just going to see what the bitches come up as.

The KC system is flawed if there are any imports in the close pedigree.
The inbreeding coefficient is just a guide and zero percent inbreeding over 5 generations of poor quality dogs will not produce quality whereas a relatively high IC with the repeated dogs being outstanding and healthy may be much better.
What is the IC of the actual puppies?

Okay bitch A has an IC around 26% and bitch B is around 3%. She actually also has another stud dog who is the offspring of the high IC dog and bitch B; his IC is 7.3%. So, assuming one of the litters has the same set of parents, they will have the same IC? The puppies aren't born yet and I don't know which dog has been mated to which bitch so I don't know.

That's a very interesting tool tho! But I am left a little confused as to whether that particular dog is gonna be a goodun. Confused.com

Exactly! A low co efficent is to be found in mongrels.. someone seeking a puppy that at least looks like it should will not find it in a mishmash pedigree of all unrelated dogs.If it is just co-efficent to be considered then please rescue a perfectly nice mongrel from a shelter.

the co-efficient tool doesn't tell you if it is going to be a good dog. You still need to see the pups, see the parents, suss out their temperaments, check the the hip scores and all the other health type checks. I would also have a look at the health issues related to cavs and and make a decision with everything considered. I would maybe go to a show or two and pick out a few that you like the look of and chat to the owners/breeders.
