like they aren't going for the cute ones that wont hurt them even by accident anyways

Could be morally better than killing them

It’s retarded and you know it. There’s rarely cases of animals just being born evil and untrainable, 99.9% of the time a dog becoming violent is due to shit owners who don’t have any right owning the breed they adopt. So humans bring too many “violent” dog breeds to life through breeding mills and back yard breeders, adopt them off to a myriad of people who neglect and sometimes abuse them, and then when they inevitably do something bad they’re subjected to life as a sex/torture slave? Does that sound like any solution to you? That being said male dogs are incredibly sexy bound up like that, and I’d love to see them getting noncon’d. But that’s just fantasy, don’t let freaks that do that IRL blur that line and justify animal abuse for you, keep in touch with reality.
