So I understand the "In Five Generations" ... That would be the dogs parents and then the parents of each the previous parents going back four more because you used 1 of the 5 to show the dogs parents. Right?

In another thread someone linked a ped for a dog. I see quite a long list. I removed the names and replaced them with a letter because I did not want to single out a dog I just want to know how to understand it. Would seeing 40 listed be worse or better than having say only 8 listed?

So lets take the first line it says 5-5 in A. Does that mean that this dog was bred back to one of its litter mates from 5 generations ago? What is a 4-4 or 3-3 or 2-2? Can there be a 1-1?

 The numbers indicate the generation.  2=parents; 3= grandparents;4= great grandparents; 5= great, great grandparents.  So, 5-5 means that the same dog shows up in the fifth generation/as the gr gr grandparent. 


2-2 is a sibling breeding, AFAIK.

That is one really long list of line-breeding, some of it pretty close.

Thank you! I'm still trying to make this harder than it needs to be in my mind. If this were my dog why is it a concern to me that a 5-5 (if I'm assuming right after what you told me) great great grandparents bred another dog? Is it simply so that I would know there is another dog out there with the same 5-5 that my dog had?

Hi,
Just look at the pedigree and you will see 3 , 4, or 5 generations.
the parents( father and mother)are  : 1
                   (grand parents)              : 2
             ( Gr. grand parents )            : 3
        (Gr. Gr. gramd parents )            : 4
( Gr. Gr. Gr.   Grand parents )           : 5

So 5-5 means, the same dog appears in the 5th. generation
in the male's and female's pedigree.

4-4 means the same dog appears in the 4th generation of both parents pedigree.
4-4,5 means that the same dog appears once in the 4th generation in the father's pedigree,
and twice in the mother's pedigree, once in the 4th. generation and once in the 5th. generation.

If the dog was bred back to It's litter mates, it would read as  4-5 or 5-5 ( X or Y) litter .

Thank you. That explains a lot.

So when I see these on a particular dog that shows related line breedings that occured prior that eventually came to a breeding that created that particular dog. Correct?

sometimes it gets even more complicated with 5,5-5

in this case the same dog is in the pedigree 3 times.

Sweet Jeazus !!!  is this an ACTUAL linebreeding report -  generated by this database????  if so --   please print the NAMES --  i need to know more about this breeding --   I doubt that it is German  --  there is lots of  3's and 2's there - and I didn't think they did that to this extent?? 
Also -- i wouldn't call this dog  linebred - (anymore)  to me -- it's INBRED.
I'm super old-school - but  to me --  linebeeding on 3-4-5 dogs in the 4th, 5th, 6th generations is one thing --- but what you represent here is pretty insane to me.  but what do I know. 
I have seen "American pedigrees' with linebreeding on the SAME DOG -- 12 TIMES in just 3 or 4 generations --  that's extremely concentrated blood that's sure to bring out the worst when you least expect it.

by contrast - here is a more "normal" linebreeding scheme -- it belongs to my West German (show-line) puppy.



in your example above - there is a pattern of  2-2, 3-3, 4-4, 5-5 -- so this tells me that the dog whos pedigree this belongs to is the result of a half-brother-half-sister breeding --  where the two dogs have either the same sire or the same dam --  even without names -- this seems obvious to me.

Siantha, re your question:
My answer:    IMO Not entirely happy - and hope it was done for good reasons.  That's
possibly the point at which line breeding gets quite close enough.  Any more is, as 
Pineridge says, INbreeding.

Now I don't personally have a huge problem with the notion of Inbreeding;  in the hands
of the genuinely experienced, careful breeder and done occasionally, it can be a useful
tool.  But  1]  it gets broadly abused as a technique,  and 2]  we now have a climate
where the great general public powered by PETA,  the RSPCA in UK, and others on the
extreme side of the Animal Rights movement  have anthropomorphasised it, and the world
breeders operate in is currently less receptive to it.  (Hows that for a bit of fence-walking ?)
