Aim: A 10-year retrospective study was undertaken to determine the prevalence of dog bites reported to the Veterinary Teaching Hospital (VTH), Ahmadu Bello University (ABU), Zaria, and to implement measures to control rabies exposure in the environment.

Materials and Methods: Data on dog bite cases, reported to the VTH of ABU, Zaria, Nigeria between January, 2002 and December, 2011, were retrieved and analyzed using Statistical Package for Social Sciences version 17.0, Chicago, IL, USA.

Result: A total of 236 dog bite-related cases was presented, of which 1.7% dogs died of rabies. The number of cases (59.7%) increased through time with the highest number (32) recorded in 2011. Majority of the cases were recorded between June and October of each year. Of the biting dogs, 22.5% were puppies (1-6 months) and 77.5% were adults (above 6 months). The human victims were 92.4%, while the dog victims were 7.6%. Eight of the dogs were stray dogs, while 228 (96.6%) were owned dogs. Of the owned dogs, 71.2% were free-roaming. Only 22% of the owned dogs were vaccinated. The most common offending breeds included the Nigerian Indigenous local breeds (73.3%), cross breeds (24.6%), Alsatians (0.8%), Terriers (0.8%), and Bulldogs (0.4%).

Conclusion: In conclusion, rabies is endemic in Zaria, Nigeria, and the incidence of dog bites is on the rise. Strict measures including vaccination of the dogs and the leash law should be adopted to prevent dog bites.
