Well, all I can tell you is no pedigree program on earth, nor any knowledgeable dogman I know, would call those two dogs "related" ...

There are 2046 dogs in a 10-gen pedigree, so (sorry) if Teal's Sarge is in there 7-gen back a couple times it means nothing.

Calling the dogs "related" would be the text book definition of a "stretch" ...
