I just find it so upsetting that a woman that lived a long life could die in such a sudden and distressing way. How awful.
It's a very difficult question. I'm a big dog-lover, I don't have a dog because I don't have the time or emotional energy to devote to making a 'good' dog. I like freedom and spontaneity. I'm not keen on getting up at 6am to deal with a puppy. I simply don't have the space in my life to ensure that a dog is a decent, well-behaved companion. So I don't have a dog.
How do we ensure that everyone is a responsible dog owner? I don't know. Unless dog-breeding and selling becomes completely government regulated, it's not possible.
The only thing I'd suggest would be societal disapproval. I did dump a friend because of their really badly behaved dog. It was unbearable to be around. It was only small, so not dangerous, but just relentless and terrible.
We're all a bit 'anti-shame' now, which in many ways I agree with, but anti-shame seems to mean 'I'm going to do exactly as I please and fuck the consequences'. I think there should be a general feeling of disapproval for thoughtless pet-ownership. One should be ashamed for having a badly controlled, unsocialised animal. It should be a cause for embarrassment.
But I don't think it is.
