Dangerous Dogs Act

On 20 June 2012 I lost my guide dog and my independence - all in the space of one horrific day. The dog attack incident that I experienced is still in my memory.
With a new administration now in post isn't it time for the Government to overhaul the laws and do more to tackle the real root of the problem, before responsible dog owners find more of their freedoms curtailed?
Pit Bulls are the most vilified and legislated-against type of dog in UK history and had the Dangerous Dogs Act done the job that Kenneth Baker and the Tory government had intended it to do, the 1991 generation would have been the last. The Act ordered all Pit Bull types to be neutered or killed.
In France a couple of years ago a baby was tragically killed by a German Shepherd. The adult in charge was arrested for not properly supervising and the dog was taken away for assessment. How revolutionary.
We need penalties for those owners who allow their dogs to attack and kill other dogs, cats, and other animals. We need better controls on dog breeding, advertising and sales. Only when we insist on better behaviour from the person on the other end of the lead will we be able to address the dangerous owner problem.
The Dangerous Dog Act misleadingly suggests this is a law only applying to certain breeds of dogs most famously the banned Pit Bull. In fact it is a law that has always applied to all owners and all dog breeds.
