Big Dog
As for pedigrees being wrong some probably are some ain’t, just like in any other breed, all pedigrees of any beeed is open to speculation.
Even if peds were 100% honest there is still admitted HEAVY inbreeding in pretty much all gamedog bloodlines, seldom were they temperament testend and ZERO health testing was done. To be fair, at the time these bloodlines were developed there were less options for health testing, but it seems that breeders now are either afraid to test their dogs or dont want to spend the money. There are plenty of stories of unstable dogs, and before you say 'those are just stories', THEY ARE ALL STORIES, much of the history of these dogs as pit dogs is anecdotal. No breed is immune to behavioral and health issues. We have more knowledge and methods of testing our dogs and bettering breeds, there is no longer any excuse not to except laziness.
