Tijuana municipal police arrested two people on Wednesday for allegedly poisoning and killing stray dogs in the Cerro Colorado neighborhood, marking one of the city’s most visible animal cruelty enforcement actions this year. Officers responded to reports from neighbors who witnessed the suspects placing poison-laced food near stray animals in the area.
Baja California’s Animal Cruelty Law Carries Prison Time
The arrests were made possible by reforms to Baja California’s penal code that criminalized animal cruelty with real penalties. In 2021, the state legislature approved changes making intentional animal abuse punishable by one to four years in prison and fines. Before those reforms, animal cruelty cases in Baja California were treated as minor administrative violations, often resulting in small fines or no consequences at all.
Poisoning stray animals has long been a quiet problem across Mexican cities, including Tijuana. Residents or business owners sometimes leave out tainted food to reduce populations of street dogs, which number in the tens of thousands across Tijuana according to local animal welfare groups. The practice kills indiscriminately, affecting owned pets that roam outdoors as well as strays.
Cerro Colorado sits in the eastern zone of Tijuana, a residential area with a mix of established homes and newer development. Neighbors in the colonia reported seeing dead dogs in recent days before contacting authorities. Their willingness to call police and provide witness statements proved critical to the arrests.
Tijuana’s municipal police have a dedicated unit for responding to animal cruelty complaints, though enforcement has been uneven. Staffing is limited, and cases often hinge on whether neighbors are willing to come forward. In this instance, community members acted quickly and provided enough evidence for officers to detain two suspects at the scene.
Tijuana Stray Dog Population Strains City Resources
Tijuana has struggled for years with its stray animal population. The city’s Centro de Control y Bienestar Animal, the municipal animal control facility on Boulevard Díaz Ordaz, handles thousands of animals annually. But its capacity is far short of the need. Local rescue organizations like Salvando Vidas Animal Rescue and Baja Dog Rescue, the latter well known among expat donors in San Diego, have filled gaps in spay, neuter, and adoption services for decades.
The poisoning problem intersects with public health concerns as well. Toxic substances left on streets or empty lots pose risks to children and wildlife, not just dogs. Rat poison and organophosphate compounds are the most commonly used agents in these cases, according to veterinarians who have treated surviving animals in the city.
Animal welfare advocates in Baja California have pushed for stronger enforcement since the 2021 legal reforms passed. Groups like the Asociación Protectora de Animales de Baja California have argued that arrests must lead to prosecution and sentencing to serve as a deterrent. In practice, many detained suspects have been released when cases stall in the courts. Prosecutors at the FGE (Baja California’s state attorney general’s office) have not published statistics on how many animal cruelty cases result in convictions.
The two suspects arrested Wednesday were turned over to the Agencia del Ministerio Público, the state prosecutor’s intake office, for formal charges. Under the current penal code, if convicted of intentional animal killing, they could face up to four years in prison. Whether the case proceeds to trial will depend on the strength of witness testimony and any physical evidence collected at the scene.
Pet Owners in Eastern Tijuana Should Take Precautions
Residents of Cerro Colorado and surrounding colonias who own dogs or cats should keep animals indoors or in enclosed yards until authorities confirm no additional poison has been placed in the area. Veterinarians in Tijuana recommend watching for symptoms of poisoning in pets: excessive drooling, vomiting, tremors, and difficulty breathing. The Hospital Veterinario UABC on the university campus in Otay provides emergency care and has experience treating poisoning cases.
Anyone who witnesses animal cruelty or finds suspicious food left in public spaces can report it to Tijuana’s 911 emergency line or directly to the municipal police animal welfare unit. Reports can be made anonymously. Providing photographs, video, and exact locations increases the likelihood of police response and successful prosecution.
The two suspects remain in custody pending formal charges. A preliminary hearing is expected within 48 hours of their detention, as required by Mexican law. This story was first reported by El Sol de Tijuana.
