The generic Pits have no pedigree. There is no way to tell if they are pure bred, or if maybe some Rottie or Mastiff, or any other breds were thrown in. Street Pits to me are the mutts bred to be junk yard dogs, or chained with tow chains in the front of your local friendly drug dealers yard. You think the owners of those mutts even knows what a pedigree is???????
Why must you continue to bash the breed? My bf Becca has a non-AKC or UKC pit bull and she is plenty pure even though she doesn't have the papers to prove it. She was recently diagnoised with lymphoma and they have spent over $2,000 to not save her but prolong her quality of life...yep sounds like a street pit to me, why waste the money on a generic pit?
You are also wrong about the Rh factor, which I have. It does not denote a blue baby but one that needs a transfusion more often than not as the mothers blood when crossing the placental barrier destroys the babies red blood cells so no iron can be made. Although you are right that no red blood cells would eventually lead to a very blue baby.
Also are you going to address the issue of Misty? The Dobe you bred that you admitted had temperment problems? Or just not bother since you don't have a good answer for that one?
