I am not a big proponent of tight linebreeding, but when I did go to linebreeding, I bred the dog I was considering, then took a daughter back to him. This type of breeding I guess could be considered tight. I was looking to see what recessives were in the dog I wanted to use.
I have done this several times in the past. The thing that I was looking for was a dog that when bred like this didn't have a large number of trash puppies.
2 out of 8, then 3 out of 7 and 5 out of 8. First number was the good pups. I stopped after this, mostly because it is hard to cull that many puppies. Took something out of me, and I pretty much stopped breeding shortly after. Probably three out of all of the culls were in bad shape, were you would put them down anyway.
Linebreeding is in my opinion used too much without knowing what bad recessives the dog has to start. There are many really good dogs out there that carry a lot of trash genetics. They start showing up in the 5th or 6th generation usually, and then you get one or two good pups out of a litter if that. I would really hesitate to breed a really tight linebred dog. Work? yes.
