Rabies Vaccination clinic at Jefferson County Dog Control:

Protect your cat, dog or ferret by keeping it up-to-date with a rabies vaccination. It's not only NYS law, but it's also a smart way to keep rabies from harming your pet and possibly your family. Pets need to be at least 3 months of age to receive their first rabies vaccine. If you have previous vaccination certificates, please bring them with you.
All pets must be securely contained or controlled at all times.
These clinics are a great way to protect your pet and to save money. Clinics are free, but a $10 donation per animal is asked if possible.
