The state-level rules every owner and walker in New Mexico should know. Local leash lengths, licensing and off-leash rules are set by each city — find those on the city pages below.
New Mexico has no dog-bite statute — it runs on case law where the owner's knowledge of a dangerous dog triggers strict liability, plus a negligence route for ineffective control.
New Mexico has no dog-bite statute — liability is built on case law and a uniform jury instruction (UJI 13-506). Under scienter / one-bite (Perkins v. Drury), the owner is liable if they knew or should have known the dog was vicious — and New Mexico courts treat that knowledge as a trigger for strict liability, not merely negligence: once knowledge is shown, the owner is strictly liable. (A victim cannot recover if they knew the dog's propensities and wantonly excited it or voluntarily put themselves in its way.) Under negligence, even without knowledge of viciousness, an owner who ineffectively controls the dog where injury is foreseeable can be liable. New Mexico firms describe the rule as reaching owners, keepers, and caretakers — so a walker who keeps or cares for the dog is within the framework.
New Mexico applies pure comparative negligence (a victim even 99% at fault recovers the remaining 1%). The Dangerous Dog Act allows a designation for an unprovoked injury, and leash rules are local (Albuquerque's HEART Ordinance, for example). The personal-injury limit is three years.
