Gaithersburg has no citywide spay/neuter mandate for pets, but City Code § 4-5(b)(5) and (e)(6) require a dog declared 'potentially dangerous' or 'dangerous' to be neutered and/or microchipped, at the owner's expense, within a period the city manager sets.
The owner(s) of any animal deemed potentially dangerous shall:(1)Keep the animal inside of the owner's residence or in a secure enclosure which will prevent direct contact between him and the public and other animals;(2)When the animal is restrained by a leash, ensure that the leash does not exceed six (6) feet in length...(5)Comply with any and all other requirements set forth by the city manager or his designee, including having the dog neutered and/or microchipped within prescribed time period at the owner's expense.

Full Breakdown
Chapter 4 does not require ordinary pet owners to spay or neuter their animals. The obligation is narrow and behavior-triggered: once the city manager designates a dog as potentially dangerous under § 4-5(a), the owner must comply with 'any and all other requirements set forth by the city manager or his designee, including having the dog neutered and/or microchipped within prescribed time period at the owner's expense' under § 4-5(b)(5). The same language applies to dogs designated fully 'dangerous' under § 4-5(e)(6). 1 requires anyone who intentionally or accidentally permits a dog or cat to breed to obtain a breeders permit, which authorizes at most one litter per female in a 12-month period, restricts breeding to females between two and six years old, and requires the mother to be microchipped and at a healthy weight before and after whelping.
Anyone without a breeders permit who ends up with a litter must instead get a litter permit within 10 days of the birth. Both permits are issued by a person the city manager designates, with fees set by council resolution.
Violations & Fines
Failing to have a designated potentially dangerous or dangerous dog neutered or microchipped as directed is grounds for the animal's permanent removal from the city under § 4-5(c) and (f). Separately, failing to obtain a required breeders or litter permit under § 4-8.1 is a municipal infraction with a fine set by city council resolution and can result in seizure and impoundment of the female animal and her litter.
