Exactly.
it's already 'law' to have dogs microchipped - my dog is microchipped, but I know so many people who haven't got their dogs microchipped. It's also 'law' to have dogs wearing an ID tag at all times when out in public, not many people do this either.
There's a man that lives near me who claims to be a 'dog trainer' - I've witnessed him fully kicking and hitting his own dogs, as well as other peoples dogs. He even does this in public! There were times he would tie them to the side of his house (not within his property, he was the end terraced house with a road next to him) and he would just leave them all day.
He never uses leads with any of them either, just walks around wanting them to follow him and if they don't, he loses it and uses violence to 'correct' them.
The RSPCA and other authorities were called, it was reported so many times. Even with video footage of his behaviour towards the dogs.
But because the dogs had food and water in the house, nothing was done.
People still use him, those of us that have witnessed what he's like (there's many of us) have tried to warn people, etc, but people don't listen, he's cheap etc.
