Walk-in preventive veterinary care near Grossmont Center in La Mesa, Vetco Vaccination Clinic operates inside the Petco pet care center at 8501 Fletcher Parkway. Core and non-core vaccine protocols cover DHPP, Bordetella, canine influenza, rabies, and FVRCP administrations, and animals presenting with abnormal findings during pre-vaccination physical exams receive referrals to full-service practices like Feathers and Fur Animal Hospital for diagnostic workups. The clinic operates under Petco's Vetco brand, a nationwide preventive-care platform whose veterinarians also prescribe monthly heartworm, flea, and tick combination preventatives including Simparica Trio and Heartgard Plus. Microchipping uses the 24PetWatch ISO-compliant transponder, and the clinic's feline leukemia and FIV screening panel pairs with same-visit supply access at Sam & Ollie for post-visit nutrition and supplement needs. SNAP 4Dx Plus combination testing screens simultaneously for heartworm antigen and antibodies to Borrelia burgdorferi, Ehrlichia canis, and Anaplasma phagocytophilum in a single in-clinic blood draw.
