Hi I am looking at a pedigree of a litter I am interested in and notice that the sire and dam both have the same dam. Is this something that I should be worried about or is this acceptable.
Cheers

If there is a record of good health, conformation and longevity and the appropriate breed health checks/tests have been done, I can't see a problem.

That would be quite tight breeding half brother & sister & if they are BCs/WSD they should be DNA screened for CEA & CL. Would be too close for me

The sire has been tested clear for CEA and CL but not the bitch. it is a repeat mating so I presume the breeder knows what they are doing, but from the comments made when I speak to her again I will ask the reasoning behind it
thanks for your help

I wonder why the bitch hasn't been DNA tested ? Still way too close for me for BC/WSD but then I only have ISDS BC's so maybe they like such close breeding with the KC version

I presume she hasn't been tested cause she is older and this is going to be her last litter. But I will add that to my list of questions, and if not happy with answers i will look else where.

OH MM and you've been so good lately lol

My one and only litter of American Cockers was the result of a half sibling to half sibling mating, the parents had the same sire. The other side of the pedigrees is completely unrelated . I did this under the close supervision of the top breeder in the breed though, so with experienced knowledge, it can be done safely.

I would ask the breeder why they have done such a mating.  It's a very useful way of fixing points in a line, but the breeder needs to have extensive knowledge of all the dogs in the pedigree.  If you think that they don't have this knowledge, and the stud dog just happens to be convenient, then I wouldn't touch the pups with a barge pole!

Depends on the breed I suppose but personally it would not cause me a problem provided you do know  the history.  I have done a mating of this type and they were one of the best litters I ever bred.

My boy is a half brother to half sister mating and he's pretty fantastic. Of course we have so far been lucky as he hasn't shown any of the 'nasties' that Cavaliers might get - and he has a suspected SM carrier in his bloodline - his breeder wouldn't have done it if she had known what people now know about SM. Still, as long as the sire and dam are tested clear for as many inherited diseases as possible it should be ok! :-)
