PITTSBURGH (AP) — Health authorities say rabies has been confirmed in a raccoon involved in an altercation with a dog in western Pennsylvania.

The Allegheny County health department said the dog involved in the incident in Upper St. Clair was up-to-date on its rabies vaccinations.

This is the first report of a rabid animal in the county this year. Last year, 25 animals were confirmed to have rabies in the county: a dozen raccoons, nine bats, two cats, a fox and a groundhog.
