licence plates for dogs

In Frankfurt they are planning to introduce a law making all dogs wear what is effectively a licence plate so that the public can report owners - well dogs - that are doing the business - without being scooped. The next thing they will be introducing is - 'On the Jobbie Fines'.

Linked to this i had always thought that castration would be the most effective way of stopping aggressive behaviour of dogs -such as pitballs. However I am informed that the European Court of Human Rights will not allow to harm the owners. Shame.
