The facts are in any given year there are about 30 or so dog bite fatalities in the US. Pit Bulls and Rotties are usually good for about 20 to 23 of these. That leaves 7 to 10 for all of the other hundreds of breeds.
Most dog breeds never kill humans. Pit Bulls do it about once every 2 weeks.
If you say so ... leave me alone now. And stay away from dogs.
