Vetco Vaccination Clinic runs walk-in, low-cost immunization sessions for dogs and cats inside the Petco at 10410 Friars Road in Grantville, San Diego, operating on a rotating schedule separate from the full-service Vetco Total Care hospital at the same address. The clinic administers core vaccines—canine distemper-parvo (DHPP), rabies, and bordetella for dogs; feline viral rhinotracheitis-calicivirus-panleukopenia (FVRCP) and rabies for cats—along with lifestyle-based add-ons such as canine influenza, leptospirosis, and Lyme disease immunizations. No appointment is required: pet owners walk in during the posted clinic window, a veterinary technician weighs the animal and reviews its vaccination history, and the attending veterinarian administers the appropriate doses on site. The 92120 ZIP code and east Friars Road location put the clinic within the Grantville commercial corridor near the SDSU campus, drawing student pet owners, Allied Gardens families, and east-side residents who need current vaccination records for dog-park access, boarding facilities, and obedience programs—including Who's Walking Who? Dog Training in San Carlos, which requires proof of current immunizations before enrollment. Vaccination packages bundle multiple immunizations into a single visit at a lower combined cost than à la carte pricing, and the clinic also provides heartworm tests and flea-and-tick preventive dispensing during the same session. Each animal receives a printed vaccination certificate with lot numbers, manufacturer details, and the administering veterinarian's signature—the documentation format required by San Diego County for rabies compliance and by most boarding and daycare facilities for admission. Pet owners stocking up on food, treats, and supplements during the same Petco visit also source raw and species-appropriate diet options at Wolf's Raw Dog Food in San Carlos, which carries frozen-raw and freeze-dried formulations alongside the conventional kibble selection inside Petco. The clinic's bordetella protocol uses the intranasal-delivery method, which triggers mucosal immunity in the upper respiratory tract within 48 to 72 hours—a faster onset than the injectable form and the format most boarding kennels require for admission clearance.
