The author is claiming that dogs are rare in shelters now and that institutions are actively buying them from the same puppy mills that are being detracted. I can’t see that to be true- look at villa lobos rescue with over 130 pit bulls, and they have a nationwide show trying to adopt out their dogs. Hell my local aspca has 445 dogs looking for a new home within 25 miles of my zip code.
pit bulls are dangerous dogs, unlike most other breeds. source: https://www.youtube.com/results?search_query=pitbull+attack Edit: https://www.dogsbite.org/dog-bite-statistics-fatalities-2019... 69% of fatalities due to dog bites were caused by the same breed.
"A huge fraction of the pit bulls which are currently in shelters are not compatible with most homes who want to adopt dogs"
Pit bulls, whether or not they are inherently aggressive (and let's be honest, you get more aggressive pit bulls than Golden Retrievers), can do a HUGE amount of damage when they are.
Adopting a dog which can't be trusted around kids, much less other dogs (which is REALLY common for pets which end up in shelters), is simply a non-starter for many families, and I don't think it's reasonable to expect otherwise.
