I'm really surprised that someone can't understand how other dog owners behave and opinions in wider society should affect rules that govern how you can live your live. This is society, this is how it works.
Don't you think that's a tad patronising? I've had almost 40 years in the legal profession, so it's safe to say that I have a very good idea about why and how laws are made in the public interest. So I repeat, there is not a cat in hells chance of any government of this country introducing a law mandating that ALL dogs should be muzzled and on a lead in ALL public places.
Proportionately, there are a small number of people who own particularly dangerous dogs. Changes to the law should focus on the dangers these people/dogs pose to the rest of us (and to our non-dangerous dogs). Yes, I agree that dog licences, controls on breeding, compulsory insurance etc should apply in respect of all dog ownership. However, I very much doubt that much will be done in that respect as there is no money for enforcement.
Bringing in a law that my toy poodle cross should be muzzled and on a lead at all times would massively impact on her well being and on that of my family. There are hundreds of thousands of similarly minded dog owners around the country. Do you honestly think any government or would be government will want to poke a wasps nest when more moderate actions can be taken which most dog owners would approve of?
And as for the comparison with legislation relating to driving, around 1700 people per annum are killed on our roads. Many thousands more are injured, either to a minor extent (e.g. whiplash) to a major extent (catastrophic injuries). ALL motor vehicles are extremely dangerous to human beings. If there were no regulation controlling their use, it would be utter carnage every single day for road users, pedestrians etc. The comparison is, quite frankly, ridiculous.
