Berkeley Humane offers free pet vaccines and microchips this weekend at 936 Carleton St.

The Berkeley-East Bay Humane Society will offer free pet vaccines and microchips this weekend at 936 Carleton St. in Berkeley, according to Patch.

The walk-in clinic runs Saturday and Sunday from 11 a.m. to 3 p.m. No appointments are necessary.

Dogs can receive rabies and DAPP vaccines. Cats can receive FVRCP vaccines. Flea and tick prevention, dewormer and microchipping are also available, the nonprofit said.

A similar event in May served 450 pets, which the organization said revealed "the tremendous need for accessible preventive veterinary care throughout the Bay Area."

"No one should have to put off a vaccine or microchip because of cost," Executive Director Jeffrey Zerwekh said in a statement. "When we make preventive care accessible, we are not only protecting the health of pets; we are helping families stay together."

All dogs must be on a leash and all cats must be in a secure carrier. Pets that appear visibly ill will not be vaccinated, and the medical team reserves the right to refuse service, the nonprofit said. The organization asked owners to bring previous vaccination records, especially if requesting a rabies shot.
