📋 Loudoun County Dog License — Quick Facts (2026)
Loudoun County Dog Licensing: What Makes It Different
Loudoun County — one of Virginia's fastest-growing counties, encompassing Leesburg, Ashburn, Sterling, and Purcellville — administers dog licenses through Loudoun County Animal Services. Like Fairfax County, Loudoun uses a calendar-year licensing system tied to the dog's rabies vaccination, rather than a fixed annual deadline like Ohio's January 31.
The $10 flat annual fee applies regardless of spay/neuter status — Virginia does not mandate a spay/neuter discount, and Loudoun County does not offer one voluntarily. The fee structure is the same across all license types: $10 per year, multiplied by the number of years purchased.
One critical detail for residents near the Loudoun-Fairfax border: a Loudoun County dog license is not valid in Fairfax County, and vice versa. Virginia localities issue their own licenses, and each is only valid within that jurisdiction. If you move from Loudoun to Fairfax (or Arlington, or any other Virginia locality), you must purchase a new license in your new jurisdiction — even if your Loudoun license hasn't expired.

- Dog information: name, breed, age, sex, color

Virginia law requires dogs to wear their license tag on a collar at all times. A dog found without a tag is treated as unlicensed even if a valid license is on file. If your dog's tag is lost, contact Animal Services for a replacement.
