Sunday, 9 to 11 a.m. in West Chester, New Castle and Georgetown. First 100 pets at each location get free chip.

The Brandywine Valley Society for the Prevention of Cruelty to Animals will hold a free microchipping clinic, thanks to funding from the Petco Foundation, from 9 to 11 a.m. Aug. 27 at all Brandywine Valley SPCA campuses.

The first 100 pets at each campus will receive a free microchip. This service includes implanting the chip, which is the size of a grain of rice and inserts painlessly between the pet’s shoulder blades, as well as registration of the chip to the pet’s owner.

Microchipping will be available at the BVSPA West Chester campus, 1212 Phoenixville Pike, West Chester, Pa.; the New Castle campus, 600 South St.; and the Georgetown campus, 22918 Dupont Blvd.
