I think the main thing we should do in terms of dog safety is bring back dog licenses. All dog owners would be required to pay for and attend training lessons and have regular appointments with a vet or the license would be withdrawn.
I am old enough to remember dog licences. They didn't work then (which is why they were abolished) and they won't work now. Every dog is required to be chipped by law, but many aren't. How would you enforce making people go to "training lessons" and would that include those of us qualified to train dogs? And you cannot force someone to go to a private business. Training, insurance, proper medical care are certainly things that I would want to see responsible dog owners doing, but you can be certain - absolutely certain - that the irresponsible owners would not not be the ones doing any of this, and they will still get their hands on dogs.
You do not manage the irresponsible by punishing the responsible - who already do all of these things and more.
As has been said on any one of the 300 dog threads in the last four days.
