The radio was awash with tales of dangerous dogs, following the case of a crazed pit bull which ran amok and savaged five policemen - http://www.bbc.co.uk/news/uk-england-london-17486343. The sad truth is that this incident says more about dog owners than dogs. I know a bit about dogs. They are not humans, they are animals. They operate on a simple set of rules. If you set the rules in such a way that they are dangerous, then they will be dangerous. Unless a dog is mentally ill (which can happen), generally it can be trained to behave. Sadly the type of people who own status dogs such as Pitbulls, don't set the dog rules which are compatable with living in a safe society. The answer is simple, as far as I'm concerned. To own a gun or car, you need a license to show that you are responsible. The same rules should apply to dogs. If you don't look after the dog, you lose your license, end of.
I wouldn't mind paying a few quid a year, so that all of the idiots who don't care for the animals are regulated. I've got a dog, a boxer. She's a lovely animal. I don't want her to be brutalised by another dog, so it would please me if idiots were banned from keeping dogs.
It isn't ever the dog, it is the owner.
