If you try to ban breeds you just get an ever-expanding list of banned breeds

Yes, that is how a banned breeds list works, and pretty much all laws. “Oh but you'll have to ban other breeds in the future!”, great! We’re not trying to write the One Law that is forever good and valid. That’s like saying, “if you ban certain activities you’ll get an ever-expanding list of crimes!”

penalise good owners alongside bad

No one has to have their beloved pet put down. The banned breeds list only “harms” breeders, and breeders are so fucking unethical and bad for dog’s welfare that I couldn’t really give a solitary fuck.

People who want dogs as a weapon will always find new breeds to abuse.

Right, but we don’t say “there’s no point in banning guns because knives still exist”, do we? We can have both sensible measures to prevent cruel owners AND restricted dangerous dog breeds can’t we?

All doggoes are good doggoes

That’s just not true, sadly. From what we know about dog breeding is that aggression is a very heritable trait, so dogs that have been bred for fighting, even with good upbringing, are inherently more likely to snap and harm someone than a dog in the same situation which was bred from less aggressive dogs.

We can do something about that, if we want to.

Yes, we can - stop breeding them. Stop selling them. Stop treating them like slaves.
