"It is extremely unlikely that they [pit bull-type dogs and Rottweilers] accounted for anywhere near 60% of dogs in the United States during that same period and, thus, there appears to be a breed-specific problem with fatalities."[8] The report's authors went on to say: "Although the fatality data are concerning, one must broaden the context to consider both fatal and nonfatal bites when deciding on a course of action. ...[A] 36% increase in medically attended bites from 1986 to 1994 draws attention to the need for an effective response, including dog bite prevention programs. Because fatal bites constitute less than 0.00001% of all dog bites annually, fatal bites have remained relatively constant over time, whereas nonfatal bites have been increasing, and fatal bites are rare at the usual political level where bite regulations are promulgated and enforced, we believe that fatal bites should not be the primary factor driving public policy regarding dog bite prevention." The report's authors suggested that "generic non–breed-specific, dangerous dog laws can be enacted that place primary responsibility for a dog's behavior on the owner, regardless of the dog's breed. In particular, targeting chronically irresponsible dog owners may be effective."
