Prince William County, VA Animal Ordinances: Mandatory Spay/Neuter (2026)

Once a general district court adjudicates a dog dangerous under Sec. 4-12, Sec. 4-13(b) imposes a compressed 30-day compliance window. ' The same 30 days also requires proof of electronic identification (microchip) registered to the owner under (b)(2), evidence of at least $100,000 in liability insurance or a surety bond covering animal bites under (b)(3), payment of a $150 fee and completion of a state dangerous-dog registration certificate under (b)(4), and posting of clearly visible warning signs at every point of entry to the home and yard under (b)(5).

Sec. 4-13(a) separately requires the owner to affix a county-issued dangerous-dog tag to the animal's collar at all times. If the owner keeps the dog outdoors unattended, Sec. 4-13(d) further requires a secure, locked enclosure built within the same 30 days. The spay/neuter and other Sec. 4-13(b) duties are conditions of keeping the animal after a dangerous adjudication, not a general licensing requirement; the county's separate dog-licensing rules under Sec. 4-23 do not require sterilization of an ordinary pet.
