Pets must be 3 months of age to receive their 1st immunization, which will afford them protection for 1 year. The next shot (booster) will afford protection for 3 years and is required one year after the first shot was given. From then on, every three years a booster should be given to protect your pet. Both initial and booster shots will be given at all clinics scheduled by Warren County Public Health. A $10.00 donation is requested; however, no one will be turned away due to financial hardship.
