No country as far as I am aware, that has banned pitbulls in the way we have, has had a success in reducing deaths by dog attacks. Many countries have scrapped breed specific legislation of that type (but it is a long way past my bedtime for that data!).
Tightening the laws before Jack Lis... would not have changed those outcomes, we would not have enacted a ban and got rid of existing dogs in that time frame, even without the pandemic.
We need to really look at what drives people to buy such dogs, to stop people keeping dogs (any dogs) in unsuitable conditions. To stop people training dogs with methods that are harmful and to do things that are dangerous.
We need to enforce legislation we already have.
All of that costs money, and require a government with a will to do it and an understanding that it is a complex issue that goes way beyond the scope of any one consultation group, approach, idea.
Education - teaching children before they turn into vulnerable young adults living in scary council flats, who buy cheap bullbreed mixes to feel safe and less alone, because a cheap to feed, hardy, loving best friend who can't be taken from you like a knife would... is extremely appealing.
Teaching kids not to approach dogs, to tell parents 'so and so has a dog' before going to their home, teaching them that dogs are sentient beings with big teeth, that need care and attention - worked into PSE, biology, geography, history... covering topics like genetics, how fear and anxiety can be bred in, how learned experience can be passed genetically. Tons of scope there to work dog safety and general knowledge in, that would help inform the next generation of potential dog owners, and this generation of potential dog victims.
Funding programs like the Dogs Trust education outreach scheme.
Properly licencing breeders - not as we currently do, from a commercial standpoint, but all breeders - and holding breeders potentially liable for their 'product' for the life of that product. Punish those producing mentally and physically unhealthy dogs.
Regulating the dog training industry so AlphaTwatMan cannot sell his incel clients a course on 'how to teach your dog to rip someones arms off'. So that knuckle dragging hard-men cannot shock and zap and garotte a dog into suppressing behaviour and storing up fear and aggression. Enforcing the animal welfare act to help police this.
Improve the lives of people who as a result of low income, life on benefits, shit education, shit childhood - feel they need to protect themselves from threat by owning a scary dog (what threat you ask, believe me when I say some peoples lives are permanently on a knife edge, expecting attack and confrontation at every turn. The less they understand, the poorer communication skills, the higher the poverty, the higher the crime rate in their area, their street, their family... the scarier life is!).
Regulate dog rescue - stop shipping in dogs from overseas for ridiculous transportation fees and no back up, no safety net for these dogs, who are purchased sight unseen from photos on the internet then dumped with owners totally not equipped to cope.
Ban the importation of dogs with their ears cut off to look scary, imported by the above AlphaTwatMan companies who train them to be at the same time a family pet, and a lethal weapon. (Seriously, no one else is importing cropped dogs but this lot!).
It's pie in the fucking sky though, it will never happen because it takes too long, takes too much money, reshuffling things, enforcing things... and it doesn't instantly LOOK (as the barrage of 'why the fuck should my child learn about dogs at school' comments that follow this will prove) like a solution to the issue that banning breeds appears to be.
