I think it is a little different if it is your own pets vs someone else’s. Why should the rest of community trust the judgment and ability of someone to retrain their dog after something like that, and their assurances that it won’t happen again?
and even then you can inly do so much.
If there’s a very high chance keeping a dog is going to result in violence being done to the people around you and their pets, maybe it shouldn’t be an option in the first place. Breeds of dogs with very high prey drives, ownership of them should probably be more restricted than it is.
