• In contrast to what has been reported in the news media, the data contained within this report CANNOT be used to infer any breed-specific risk for dog bite fatalities (e.g., neither pit bull-type dogs nor Rottweilers can be said to be more “dangerous” than any other breed based on the contents of this report). To obtain such risk information it would be necessary to know the numbers of each breed currently residing in the United States. Such information is not available.
• Data in this report indicate that the number of dogs of a given breed associated with fatal human attacks varies over time, further suggesting that such data should not be used to support the inherent “dangerousness” of any particular breed. More than 25 breeds have been involved in fatal human attacks over the 20-year period summarized in this report.
• Fatal attacks represent a small proportion of dog bite injuries to humans and, therefore, should not be the primary factor driving public policy concerning dangerous dogs.
• Strategies that can be used in an effort to prevent dog bites include enforcement of generic, non-breed-specific dangerous dog laws, with an emphasis on chronically irresponsible owners; enforcement of animal control ordinances such as leash laws; prohibition of dog fighting; encouraging neutering; and school- based and adult education programs that teach pet selection strategies, pet care and responsibility, and bite prevention.

Another concern is that a ban on a specific breed might cause people who want a dangerous dog to simply turn to another breed for the same qualities they sought in the original dog (eg, large size, aggression easily fostered). Breed-specific legislation does not address the fact that a dog of any breed can become dangerous when bred or trained to be aggressive. From a scientific point of view, we are unaware of any formal evaluation of the effectiveness of breed-specific legislation in preventing fatal or nonfatal dog bites.
