Shots For Pets in Bonita has operated as a traveling low-cost vaccination clinic since 1981, running walk-in clinics at the Pet Supply storefront on Bonita Road and rotating through pet stores, feed stores, and boarding facilities across San Diego County. The veterinarians administer core vaccines — rabies, DHPP, bordetella — plus less common protocols like rattlesnake antivenom immunization, issuing the vaccination certificates that boarding facilities such as SDRagdolls require before accepting overnight guests. No exam fee is charged for vaccination-only visits, and each animal receives a permanent vaccination-history folder for long-term record keeping. The clinic also provides microchipping, de-worming, and flea-and-tick preventive dispensing at every stop on its rotating calendar. Post-vaccination socialization at off-leash areas such as Town Center Dog Park in the Otay Ranch area becomes safe once core immunity develops roughly two weeks after the final booster in a puppy series. The highest-demand protocol is the full puppy vaccination series — a three-to-four-visit sequence of DHPP boosters at three-to-four-week intervals plus a rabies dose at 16 weeks — calibrated to the antibody-fade window when maternal immunity wanes and active immunity must take over.
