During the month of May, owners of Chihuahuas and Chihuahua mixes can get their pets spayed or neutered for free as part of “Chihuahuas de Mayo.” The program is intended to educate the public regarding the startling number of chi-chis and chi-chi mixes living in shelters — as many as 30 percent of all shelter dogs are of wee stature. Pet owners must reside in Santa Barbara County to qualify; surgeries will be provided for the first 400 dogs signed up. To make an appointment, contact one of the following participating facilities: the County Humane Societies in Santa Maria (349-3435), Santa Ynez (688-8224), and Santa Barbara (964-4777 x20), as well as CARE4Paws (968-2273) and S.B. County Animal Services, Santa Maria (934-6968). For more information, visit projectpetsafe.org.
