I LOVE big dogs and would love to have one, but this is just an example of how you MUST be in control of your animal at all times--and I'm not sure I have the wherewithal to be able to control a big dog. Despite what people say, you can never completely trust an animal. As I have always said about my animals, "S/he hasn't bitten/scratched anyone--YET." Too many people--and I'm making assumptions about the dog's owner, now--don't do enough research about a dog/breed before getting one. Many people just go by what looks cool or is the 'in' thing at the time. But there is much, much more that is involved in RESPONSIBLE pet ownership and it's time people started to realize this. Maybe we should have to have a license in order to GET an animal, rather than waiting until we already have one.
Hopefully, the vet will be fine--and the chances are that he will. This could have been much worse, but for him, it was terrifying enough. I don't even WANT to think what the results would have been if the dog had attacked a child! Horrifying!
*In no way am I trying to vilify Rottweilers OR any big-breed dogs. This is only mentioned as it IS relevant to the story. Little dogs can do just as much damage as a big dog--in different ways, of course.
