What I can't understand (re the recent case in Dundee of a small girl being mauled by 3 rotweillors) is why we can't have a law limiting the number of these dogs people are allowed to own. I'm a dog owner, but why does anyone need/want 3 dogs, let alone rotweillors.
It would be so easy to police, rather than going on a case-by-case basis, if you had to have a license for your dog, and, in the case of dangerous breeds, had to prove your case for owning more than one (or even just one IMO).
