This is how my father explained inbreeding and outcross. (My family primarily bred hunting dogs and performance horses(Quarter and Thoroughbred).
Inbreeding is sire/daughter - dam/son - half sibling/half sibling - full sibling/full sibling - uncle or aunt/niece-nephew with each half of the pedigree being doubled up on...
Outcrossing was to breed two animals that had no common relatives on either side of the pedigree.
Use of kennel names can be misleading if one doesn't know who actually bred the dogs, how many pups were in a litter, who bought them and what if any kennel name was used when they were registered. For example: Annaconti's Levi Garrett. How many GSP folks would recognize the Annaconti kennel name? Yet this dog came from two very recognizable kennel/bloodlines Weinland and Lieblinghaus.
Inbreeding is not for the faint of heart as any problems in the genetic make-up will usually surface relatively quick. On the flip side it can also bring forth desired results as well.
About the Argentina litter...If her bitch shares no common relatives with the rest of the dogs in the pedigree, "the lady doth protest too much..."
