Stricter laws regarding how dogs are handled in public is a must, i.e - leads on, etc.
Some councils already have other things in place but don't have the funds/time to enforce them etc.
Back to the statistics though, I don't think it's fair to brand all dogs as being 'bad' based off the small percentage that cause harm. YES, all dogs, big or small, are capable of causing harm - but all humans are also capable of causing harm. It's solely on an individual basis.
I also think that certain breeds are 'hyped up' a lot and become really popular suddenly, almost like a trend, so for example, people all seem to want XL bully's at the moment - therefor statistically, that breed will be named mostly for attacks, etc.
Personally - I love dogs, of all sizes, I absolutely adore them. When they're in the correct environment for their breed & temperament, they flourish and are such beautiful souls.
I myself have been severely attacked by a dog - twice.
Once was when I was 7 years old walking to school with my mum, a neighbours Rottweiler got loose and attacked me, my mum & a neighbour that tried to help. The reason that dog stopped attacking us, was because of our dog - my mum used to walk me to school with our family dog, and during this attack, our dog kept putting herself between me and the other dog, and she eventually bit the other dog and scared it away. The owner of said dog had been reported multiple times due to her treatment towards animals (locking multiple dogs inside a cage under the stairs).
The second time, we were on holiday and I was randomly attacked by a small mixed breed dog. I had puncture wounds to my head, face, neck and chest. I was simply sat down and the dog came out of nowhere and went crazy. I had to have rabies shots, but the wounds luckily healed well.
Both events scared me, however, both dogs were also poorly treated by their owners. One dog was a large breed, the other was tiny.
Growing up - we always had pets. Cats, fish, snakes, lizards, birds, rodents and dogs. We only ever had 1 dog at any time, usually a large breed dog.
All dogs I grew up with were trained to high standards by my parents, they always chose breeds that fit our household, and the dogs would have set boundaries - as my safety and my siblings safety always came first. But - my parents also taught myself and my siblings how to behave around dogs and how not to behave.
The experiences I had with the aggressive dogs, scared me massively, I saw the horrible side of a dog that ALL dogs have the capability of showing. However, I've come across so many dogs in my life, strangers dogs, friends dogs, family members dogs, stray dogs and so on. Of all breeds, sizes, temperaments etc. And out of all of them - only those 2 ever scared me.
I am now a mother myself, and I have a large dog. I've put a lot of time and other resources into training her, ensuring she's socialised in every possible way (as socialising doesn't just mean people/other pets etc) and I work hard to ensure that the needs of my dog are met.
When out on walks, I always come across dogs, some amazing and beautiful, some are massive dickheads like their owners. I remain wary of dogs that I am unfamiliar with, however I don't ever presume all dogs are bad, because they're not. When treated properly, trained properly, etc, I think they're great.
It's like with people, I was once on my way home from work after a long 12 hour shift - I was followed and then attacked by a random man. Yes it terrified me and took me a long long time to get over, however, I don't look at every man I see and presume they are going to do the same. All people are capable of it, men and women. I remain wary and keep my wits about me.
