Pomeranian!?

Those things are like 10 lbs! Please find me one case where a Pom put someone in the hosptial.

As far as attacks that actually injure people go, even though Pit Bull Terriers account for a small minority of the dogs in existance. However, as recently as 2003, when 24 people were killed by dog attacks, 1/3 of those were caused by Pitt Bull Terriers (that's 8 deaths). 6 occured by rottweilers, the rest were caused by other breeds.

I'd say that both Pits and Rotts are unsafe. Why would anyone have those around their home when safer breeds are available?

Just do a google search for "dog attacks" and see how many times Pit Bulls come up compared to other dogs... why is that? It's certainly a documented fact that their attacks are more fatal than attacks by other dogs.
