Rabies Vaccination Required by Colorado Law
Hello Fremont County pet families! Just a friendly reminder that in Colorado, all dogs and cats aged 4 months or older are required by law to be vaccinated against rabies. This helps protect your pet, your family, and our community from this serious disease. 🛡️
What the law says:
“The board of health of an organized health department or a county board of health...order that all dogs, cats, other pet animals, or other mammals in the county or district be vaccinated against rabies …” and that vaccines be administered by a licensed veterinarian.
— Colorado Revised Statutes § 25-4-607
What this means for you and your pets:
If your dog or cat is 4 months old or older, they must have a rabies vaccine.
If you’ve recently adopted a pet, moved into a new county, or are not sure about their vaccine status — please check!
Why it matters:
Rabies is almost always fatal once symptoms appear. Vaccination is safe, effective, and the best way to prevent this disease in your pet and people. Plus, staying compliant with state law avoids penalties and ensures public safety.
If you’re due for your pet’s rabies booster or need to schedule a vaccine, call us or send us a message. We’re here to help!
Stay safe & healthy,
