Question on inbreeding

[mrudderman24]

My dog's mother is Alexis. In the attached pedigree, the dog Ruler Oney Vom Hallynn Haus, appears in two different sections of the pedigree. I think it is her great grandfather. Is this considered inbreeding? From what I know, he was an almost pure tan GSD. So I'm assuming that's why they introduced him twice? I have seen his offspring and they are almost pure tan GSDs with black muzzles, beautiful (I know nothing about pedigrees or breeding )

That's linebreeding... not inbreeding.

That far back, it's considered linebreeding, not inbreeding. Your dog is linebred 4-4 on Ruler Oney. The parents are position 1, grandparents are 2, great-grandparents are 3, etc. That dog appears twice in position 4, so the linebreeding is 4-4.

That type of linebreeding is not at all uncommon in GSDs. The net genetic effect is about the same as if he were one generation closer, so a great-grandparent instead of a great-great grandparent.

My puppy has a 3-3 linebreeding. It's not uncommon. Inbreeding would be brother-sister, mother-son, etc.

Linebreeding isn't a bad thing either as long as the breeder knows what they're doing. The breeding should always be done with a purpose.

A good question to ask your breeder if you haven't already is why they chose to linebreed that specific dog. Was there a purpose to it?

You guys are awesome, thanks!

ps: How do I read AKC registration numbers and dates properly? The date in the AKC registration, is that the birthdate? Or is it the date they were registered. I purchased Ruler's pedigree from AKC's website. It lists his birthdate as 1/20/98. Yet the date after his DL number is 10-00?

Are you sure that is not 3-3. If the parents are 1, the grand parents are 2. This is the great grand-sire.

3-3 is considered acceptable in Germany. But, I hope they are using the dog for more than the color factor. It is good to find out all you can about dogs that appear more than once in 3-4 generations, sometimes even further back. More than physical traits are passed on through the genes.

Alexis, the dog whose pedigree was posted, is 3-3. She is the OP's dog's mom, so the OP's dog is 4-4.

Ok, thanks, you're right. I was looking at the pedigree as the pedigree for her dog, not the mother.

The date behind the name is most likely the date he was entered into the stud book.

Unless the OP's dog carries this dog in his sire also then the OP's dog would not be considered 4-4. The linebreeding reflects on the linebreedings between sire and dam and not any linebreeding found exclusively in either parent. Hope that makes sense.
