Summary
Washington, D.C. does not require microchips for ordinary pets, but a dog ruled potentially dangerous must be implanted with one before the Mayor issues its registration certificate.

(7) The potentially dangerous dog has been implanted with a microchip containing owner identification information; and (8) The owner has written permission of the property owner...
Full Breakdown
The District has no general microchipping mandate for dogs or cats: owners instead must license and collar their pets under D.C. Code § 8-1804. Microchipping only becomes mandatory once a dog is determined potentially dangerous: under D.C. Code § 8-1904(a)(7), the Mayor cannot issue that dog's certificate of registration unless it has been implanted with a microchip containing owner identification information, alongside spay/neuter, current vaccination, and enclosure requirements. Separately, when any animal is impounded, D.C. Code § 8-1805(b) requires the Mayor to scan it for a microchip while trying to locate the owner.
Violations & Fines
Failing to meet the § 8-1904 registration requirements, including microchipping, means the Mayor cannot register a potentially dangerous dog, and keeping such a dog without a valid certificate is a misdemeanor under § 8-1905(1) and § 8-1906, punishable by a fine up to $500 (first offense) or $1,000 (subsequent) and up to 90 days imprisonment.
