Summary
Carroll County doesn't require microchips for every pet, but once the Animal Care and Control Authority declares an animal vicious and appeals run out, the owner must have it microchipped within ten days and hand over the chip data.
Upon determination by the Animal Care and Control Authority that an animal is vicious and after the exhaustion of any appeals, the owner shall have the animal microchipped for permanent identification by a licensed veterinarian within ten days and the corresponding microchip data shall be given to the Animal Care and Control Authority.

Full Breakdown
08(A), the vicious-animal statute, not a stand-alone pet-identification rule. 15, so an owner who appeals a vicious determination doesn't have to chip the animal until that appeal is resolved against them. The same subsection adds an ongoing disclosure duty: if the owner later sells or gives away an animal that has been determined vicious or potentially dangerous, the owner must notify the Authority in writing with the new owner's name and address, and must tell that new owner in writing about the animal's vicious history.
02, ties dog identification to a numbered tag on the collar, not a chip, so microchipping in Carroll County is specifically an aftermath of a vicious determination rather than a universal pet requirement.
Violations & Fines
Failing to microchip a declared vicious animal within the ten-day window, or failing to give written notice to the Authority and a new owner before transferring it, is enforceable as a Chapter 90 violation under § 90.99: up to 30 days in the county jail, a fine of up to $500, or both, with continuing noncompliance counted as a separate violation each day.
