Summary
Trenton requires every dog on a public street or in a public place to either wear a securely fastened muzzle covering the whole mouth, or be on a leash no longer than three feet and controlled by a person at least 14 years old, under § 21-5. Police canine corps dogs under Police Department supervision are the only exemption.
No person owning, keeping or harboring any dog, male or female, shall permit it to run at large or to accompany him/her on or in any public street or public place within the City at any time unless such dog shall wear a substantial muzzle of adequate size securely fastened about the nose and covering the whole mouth, except that a dog shall be permitted on or in the streets or public places within the City without such muzzle if it is on a leash not exceeding three feet in length and is under the control of a competent person above the age of 14 years, so as to prevent injury to persons or property, and provided that such dog is not of a vicious propensity. Police canine corps dogs under the direct control and supervision of Police Department personnel shall be exempt from the provisions herein.

Full Breakdown
' That three-foot leash cap is shorter than the standard six-foot leash length common in many neighboring municipalities, meaning a Trenton dog owner using a typical retractable or six-foot leash without a muzzle is technically not in compliance with § 21-5's letter. The only exemption written into the section covers police canine corps dogs under the direct control and supervision of Police Department personnel; there is no exemption for service dogs or off-leash areas, because Trenton's chapter does not establish any dog parks in this article.
Violations & Fines
Violations of § 21-5 are punishable under Article I's general penalty at § 21-16, which routes to Chapter 1, Article III's citywide maximum: a fine up to $2,000, up to 90 days in jail, or up to 90 days of community service. A female dog in heat found at large under § 21-6 can additionally be impounded and, after seven days unclaimed, destroyed.
