I'm very sorry to hear that, it must have been absolutely horrific and I don't blame you for feeling the way you do. However, I'd just like to point out that there are many, many, MANY breeds (I'd dare say most breeds) that have had individuals from that breed kill other dogs. I am an animal control officer - trust me, this behaviour is not limited to bull breeds. In fact they rate very low in attacks. Any responsible pit owner will recognize that they *can* be quick to fire up with other dogs (the old saying - they won't necessarily start a fight but they will finish it), and this is something that we are mindful of. We socialize our dogs, train them, and raise well balanced, friendly dogs. That said, my dog loves other dogs to a fault and has never ever responded even when other dogs have been aggressive towards her. Without knowing more about your scenarios I can't comment, but NO well socialized dog that has never shown warning signs before will suddenly turn around and kill another dog for no reason. These dogs you mention would have shown many, many warning signs before it actually getting to that point, and the owner was the irresponsible one for not recognizing/acknowledging those warning signs and putting the dog in a situation where this could happen. A typical case of 'oh, he'd never hurt a fly' when their dog has shown severe warning signs (I see this all the time in my job with every breed you can imagine). Again, I'm sorry and after what you've experienced I wouldn't blame you for not liking the breed, but at the end of the day would you write off all black people because you'd been robbed twice? There are bad examples in every breed, and every breed can and does kill other dogs. I'm not here to change your mind, but just to highlight that at the end of the day Breed bans have been proven to be completely ineffective in reduce dog attacks. Every other country that has had this legislation has either repealed it or is in the process of repealing it. It doesn't protect dogs, it doesn't protect people - it costs tens of thousands of dollars in tax payers money to implement and it kills loving family pets. There are models of animal management out there that are proven to significantly reduce dog bites in the community that do not include any type of breed - specific legislation, they work because they target the real problem- the owners.
