Serial & rampage dog attack data
From ANIMAL PEOPLE, January/February 2002:
Pit bull terriers and Rottweilers together appear to commit
about two-thirds of the reported serial attacks on humans (65%), and
more than three-fourths of the rampage attacks (79%), ANIMAL PEOPLE
has learned, in a review of files on approximately 1,500 dog attacks
in cases in which a person was killed or maimed, or police shot the
dog.
Serial attacks are defined as instances of a dog injuring
someone after having injured a person or an animal on a previous
occasion. ANIMAL PEOPLE found that about 5% of the dogs involved in
life-threatening or fatal attacks on humans, or shot by police while
attacking, had attacked a person or killed a pet on an earlier
occasion.
