Conclusions—Although fatal attacks on humansappear to be a breed-specific problem (pit bull-typedogs and Rottweilers), other breeds may bite andcause fatalities at higher rates. Because of difficultiesinherent in determining a dog’s breed with certainty,enforcement of breed-specific ordinances raises con-stitutional and practical issues. Fatal attacks representa small proportion of dog bite injuries to humans and,therefore, should not be the primary factor drivingpublic policy concerning dangerous dogs. Many practi-cal alternatives to breed-specific ordinances exist andhold promise for prevention of dog bites. (J Am VetMed
