Summary
San Marcos dogs must stay confined by a sound fence or enclosure on the owner's property, or be continually restrained on a leash or chain whenever they're off it.
At large means an animal (excluding sterilized cats) that meets one of the following criteria: (1) On premises of owner: Any animal not confined to the premises of the owner by some physical means of sufficient height, strength, length, or manner of construction to preclude the animal from leaving the premises of the owner... (2) Off premises of owner: Any animal which is not physically and continually restrained by some person by means of a leash or chain of proper strength and length that precludes the animal from making unsolicited contact with any person, their clothing, their property, or their premises.

Full Breakdown
City code defines "at large" two ways: on the owner's premises, an animal must be confined by a fence or enclosure sturdy and tall enough to keep it in, a fence that's too short or in disrepair still counts as at large. Off the premises, the animal must be physically and continually restrained by leash or chain of sufficient strength and length to prevent unsolicited contact with people or property. Letting a dog run at large is an offense under Sec. 6.009(c)(17), and animal control officers may impound loose dogs under Sec. 6.003(f)(3). Dogs inside a city-owned or city-sanctioned dog park with their owner present are exempt.
Violations & Fines
General Code penalty of up to $500 per offense (Sec. 1.015(b)); impoundment of the dog; a second at-large impoundment requires the owner to sign a mandatory sterilization agreement (Sec. 6.030).
