Of course there are dangerous dogs, you don't see people breeding bad ass giant protective golden retrievers because there's no market for them but mean oversized "pit bulls" sell for big money to idiots with ego issues who encourage bad behavior and breed more unstable dogs. Most people have no idea my dogs are APBT because their idea of a "pit bull" is a 100+ pound blue dog that looks like a friggin mastiff and was produced solely for a look. Bad breeding = bad dogs and all the training and raising isn't going to change a messed up dog.

Looking at what a few decades of byb have done to "pit bulls" is horrifying, even scarier is the trend I'm seeing of actual guardian breeds (presas, filas, cane corsos, etc) heading the same way. A well bred APBT is a medium sized dog that loves people and tends to have animal and dog aggression, a well bred mastiff is a giant breed with a tendency to wariness around strangers. I hate seeing byb giant breed dogs in the hands of idiots, it's a disaster waiting to happen. I would love a molosser someday but only from a very reputable breeder, you couldn't pay me to take one from most of the "breeders" I see advertising.
