A fight between a dog and a raccoon Saturday in Royalton ended with the dog's owner shooting the raccoon to death, Niagara County Environmental Health Director Paul R. Dicky said Thursday.

The raccoon later tested positive for rabies, making it the second confirmed case of a rabid animal in the county this year.

The incident occurred on Mountain Road, about a mile south of Middleport. The dog had been vaccinated against rabies, but it was still required to receive a booster shot and be kept under observation for 45 days, the Health Department announced.

The first rabies case in the county this year came last month, when a raccoon bit two sheep on a farm on Ditch Road, also in Royalton.

A free rabies vaccination clinic for dogs, cats and ferrets will be held from 9 to 11 a.m. July 13 at the Royalton Highway Department, 5316 Royalton Center Road. It's open to all Niagara County residents.
