In the local council I am in in Australia, we seem to have more dog ownership laws than the UK. This doesn't stop attacks.
Having had a dog that was attacked whilst out walking on a leash, I can say that the council response was fast. I called at 6.45am and the call was answered. The local ranger came to my house at 8am but we were at the vet. By the time he returned at 12 he had seen the dog, taken pictures and spoken to the witness. The dog was declared dangerous. From memory I was notified of this decision 3 days after the attack.
Dangerous dogs have onerous conditions to abide by including being kept in a defined enclosure, muzzled when out, high annual registration fees. The owners opted to PTS.
In general, all dogs have to be on leash unless in a designated off leash area. Dog laws are set by councils, so can take into account requirements of dogs in their area eg if farmland, then working dog laws / exceptions.
There are also laws around compulsory registration, compulsory microchipping, requirement to have a supply number recorded with the microchip information (ie owner contact details). The supply number legislation is only recent but the data from that will be very interesting to see in a few years around the ultimate source of dogs in rehoming facilities.
With all of that, can you believe that dogs are found loose without registration or microchip.
Can you also believe that some councils approve puppy farming facilities?

It's irresponsible breeding at it's worst. Those dogs will not be socialised and will not have a nice life.
