As I’ve said this thread is pointless and it will achieve absolutely diddly squat. Guaranteed.
Of course it won't.
This is an internet forum. No-one has any power here to actually effect change out there.
Because you'd need a licence which can easily be checked and various breeds would be banned and couldn't be licenced.
Your dog's microchip, and thus your registration details, can already be checked there and then with a simple handheld scanner by any Police officer, dog warden or veterinarian that has one. You can even buy your own for about £40.
It's as simple as a cop checking your car registration plate.
I'm talking about licencing all breeders and all owners and simply not allowing illegal breeds to be registered. If you buy an illegal dog from an unlicensed breeder and you then can't register it then that poses an obvious problem... you can quite easily kill a lot of demand for those dogs as many people won't want a pet that could be taken from them at random.
That won't actually stop anyone from buying an illegal dog, and the likelihood of being stopped for a spot check by a cop will be so low, they can walk around without any fear.
Dogs can already be taken if the authorities
merely suspect it's a banned breed or a dangerous dog.
To use your car analogy - There are over half a million unlicenced drivers, almost three quarters of a million untaxed vehicles, and double that number of uninsured drivers currently on the road.
This is despite licencing, legislation and a plethora of automated systems that should be seeing law-breaking drivers all caught and prosecuted without an officer even needing to lay actual hands on collars...
So what makes you think the very small number of problem dog-owners will magically start following your new laws?
Nope, there was widespread opposition to it, smokers did it begrudgingly as pubs forced them to because allowing it would lead to enforcement action against the premises.
There was initial criticism over the planned partial ban, which gradually turned to more widespread support, among both smokers and non-smokers, once it was a near-total ban.
Support stood around 78% in 2007 when the ban came in, rising to 83% by 2017.
And again, peer pressure is one of the biggest factors in preventing drink-driving, as well as many other undesirable behaviours... yet you seem so very averse to making use of that power, for some strange reason.
